"It's good for health?" The tall girl with a Keroro pouch asked, as she stares at the suspicious bottle, with the label 'Health Drink' on it. No nutrition fact or any other information about the drink.

"Yes. Our producer gives a bottle to try out but we never really got to try it. Do you really want to buy it? I can't really guarantee about the effect and taste." The staff replied, taking the bottle from the girl and looking at it, feeling suspicious about it.

"... I... I think I will try it out and tell you if it's good next time." The girl replied with a smile that charms the staff instantly. The staff loses his sense and blushed, offering to give the girl the drink for free. After all, it's a great honor to meet her, since she's a member of a popular girl group in their country. After some debate, the girl sighed as she accepted the offer to take the drink for free. Together with her manager, they headed back to their dorm.

"What's this, Seo?" A tall girl picks out the bottle and looks at it.

"I don't know, unnie. The staff at the mart gives it to me for free, saying that it's a new product that their producer give them to try." The girl replied, taking the bottle from the tall girl and opening it to see its content. "Smells sweet..."

"And you just bring it home without knowing what kind of substance this is?"

"It's labeled health drink."

"You and your obsession over health..." The tall girl sighed, snatching the bottle over and drinking it.

"Unnie! Don't drink all of it!" Seohyun cried out, trying to stop the shikshin from gulping down the whole bottle. The rest of the group appear in the kitchen, curious about the slight commotion in the kitchen.

"What's going on?" A short girl asked.

"Taeyeon unnie, Sooyoung unnie is drinking all of that drink that I brought home for myself!" Seohyun complaint, pointing to the tall girl with a pout. Taeyeon sighed and jabbed Sooyoung's stomach, causing the girl to spit out some of the drink.

"Yah!" Sooyoung glared at the short girl, rubbing her stomach. However, before she can continue saying anything, her stomach starts to ache. Without a word, she pushes the girls aside and runs for the bathroom.

"Sooyoung unnie?" The doe-eye girl knocks on the door worriedly, and the girls gathered outside the bathroom. Suddenly, they hear someone crying in the bathroom, but it doesn't sound like the tall girl. In fact, it sounds like a little kid. "Unnie?"

"Yoong~" The door opens and they see no one but a crying kid in front of them. A kid that resembles the tall girl greatly. Yoona raised her eyebrows as she carries the kid up, trying to figure out who is this kid. "Yoong..."

"Sooyoung unnie...?" Yoona stares at the kid, feeling puzzled. "What's... going on...?"

"I don't know... After I drank that drink, I got a stomachache and the next thing I know, is that I start to shrink in size... I'm even shorter than those two danshins now!" The kid continues to cry and the doe-eye girl hugs her closer, patting her to comfort her.

"What kind of drink is that, Seo?" Taeyeon asked, not wanting to believe what just happened. It's too ridiculous and absurd for her to believe it.

"I... I don't know... It's labeled Health Drink..." Seohyun replied, feeling confused and sorry. "I'm sorry, unnie..."

"It's partly her fault for being so greedy..." Another shorter girl replied.

"YAH! LEE SOONKYU!" The kid screamed, pointing at the girl while still in Yoona's embrace.

"Kid, be respectful to your unnie." Sunny smirks, patting the kid.

"Seo, go and find out about the drink from the mart. Go with her, Yul." Taeyeon commanded and the two taller girls went out quickly. "Go and find some clothes for this kid, Fany. Her clothes are too big for her now... Go with her, Sunny."

"I will go with them!" Jessica volunteered and went out with the two of them.

"Babysits this kid, Yoona." Lastly, Taeyeon turns to the doe-eye girl and looks at the kid in her arms. "We will just wait for the rest to come back."

"... Okay, unnie." Yoona nodded, sitting down on the chair in the kitchen with the kid on her lap. Hyoyeon couldn't help but to try and play with the kid, who is obviously annoyed.

"I'm not a kid!" Sooyoung snapped at the girl angrily.

"Sorry. Can't help it when I sees you like this." Hyoyeon shrugged and sat down, not going to play with Sooyoung anymore. Taeyeon picks up the bottle and examines it closely, but she's unable to find any clue about it. Everything about this drink is suspicious. Without realizing it herself, Yoona starts to pat Sooyoung gently on her head as she stares blankly into the air, and Sooyoung, being sensitive right now, wanted to ask her to stop. But when Sooyoung turns her head, she realizes how close her face is to the doe-eye girl's chest and she blushed instantly, looking away.

"Does it feel good to be a kid?" Hyoyeon teased after seeing that, smirking at the kid.

"W... Why... Why would it be?!" Sooyoung stuttered, not daring to turn her head anymore. Yoona presses her own chest against Sooyoung's head unintentionally as she leans forward to grab the bread on the table, causing the kid to turn even redder.

'M... May... Maybe it's pretty nice to become a kid...' Sooyoung thought, looking up at the doe-eye girl and smiling without realizing. Hyoyeon faked a cough and smirked at her, seeming to know what she's thinking about. After all, everyone in the group except for Yoona knows about the fact that Sooyoung has special feelings towards the doe-eye girl.

"You want some bread, unnie?" Yoona asked, feeling weird to call a kid unnie. "Can I just call you Sooyoung...? It's kind of weird to call a kid unnie..."

"Not you too... But yes. Didn't I say that you can stop calling me unnie since don't know how long ago...?" Sooyoung sighed. "And yes, bread please." And she kind of regret saying yes, as the girl leans forward to grab a bread for her. "D... Don't lean on me like this, Yoong!" Instinctively, Sooyoung stretches both her arms out to push the girl, and shocked when it came in contact with something soft.

"UNNIE!" Yoona screamed, almost standing up and causing the kid to fall. She covers her chest and blushed madly, staring at the kid in disbelief.

"C... Crap! Sorry! I... I forget that I'm a kid right now..." Sooyoung jumps off Yoona's lap quickly and did a formal bow as she apologized. Yoona cleared slightly and fiddled with the bread in her hand. Taeyeon sighed and went on to carry Sooyoung up, putting the latter on a chair beside Yoona and giving her a bread.

"Why are they taking so long?" Taeyeon murmured, sitting down also.

"Unnie! Unnie!" Just then, the front door swings open and Seohyun appears in the kitchen, panting non-stop. "Ba... Bad news, unnie..."

"What?!" Sooyoung stood up on her chair immediately, feeling nervous and upset.

"That drink, turns the one that drink it into a five year old kid... And apparently, the mart couldn't get in contact with the producer that gave them the drink..." Seohyun continues after calming down her breathing rate, not daring to look at the kid in her eyes.

"W... What...?!" Sooyoung almost fall off the chair upon hearing that news. Yoona caught her in time and settled her down on the chair properly, patting the girl gently.

"It's a mistake made by the staff, as he didn't know that he's not suppose to sell the drink. Apparently, their manager tried it and turned into a kid before he could inform his staffs about the effect." Yuri came in shortly after, explaining further. "But according to the manager, she will turn back to normal in a month time. The effect will wear off slowly."

"Really?" Hyoyeon questioned and both Yuri and Seohyun nodded. "But what about the activities during this one month? We can't let her appear in this state, can we?"

"We have to leave her out..." Taeyeon sighed.

"What about the fans, unnie? They will be worried if they don't see Sooyoung unnie suddenly." Yoona pointed out.

"We have to come up with something to cover it up. We have no choice." Taeyeon replied, walking out of the kitchen to make a call. She called their manager and informed him about Sooyoung's inability to participate in the month's activities. Sunny, Tiffany and Jessica came back soon after, with kids' clothing in their hands, mostly pink.

"I tried to stop her from grabbing the pink ones." Jessica explained, sighing at the clothes in her hands. "At least it's not ALL pink now."

"My mistake for asking Fany to go..." Taeyeon smacks her own forehead. "Soo, get changed. It's not nice to see you in that oversized shirt that is going to fall off any time soon." She handed the kid one of the non-pink clothes and asked Yoona to bring the kid into the room. Yoona left her alone in the room to change and carried her out again when she's done.

"Aww~ so cuteeee~" Hyoyeon squealed, when she sees kid Sooyoung dressed in a hoodie with cat ears. There's even a tail coming out from the back.

"What's this...?" Sooyoung asked, feeling embarrassed. She turns around and wraps her tiny arms around Yoona's neck gently, to hide her face from the rest.

"I said it. I tried to stop Fany but she keeps grabbing whatever she thinks is nice. So even though it's not pink, it's THAT kind of clothes. There's even a rabbit ears one, bear too." Jessica shrugs.

"I'm not Kyungsan, Fany ah!" Sooyoung screamed, frowning.

"But you're a kid now." Tiffany grins, happy about the clothes that they got for Sooyoung.

"Taengoo, she can't go for activities and we can't leave her to stay here on her own while we're all out, can we?" Sunny asked, and Taeyeon stares at her for a moment.

"Official website. Now." Taeyeon seems to have gotten an idea somehow. She took a picture of Yoona carrying Sooyoung and went on the computer, posting something on their official web page. The girls gathered behind her, reading as she types out a message.

'Ta-da~! Isn't the kid cute? Yoona's little cousin had visited us and she will be staying with us for a while. Say hi to her when you see her next time~!'

"Taeyeon!" Sooyoung stared hard at the message.

"Or do you want to go back to your own place and stay with your family for the time being?" Taeyeon asked, not clicking on the post button yet.

"... Don't want to... " Sooyoung replied, clinging to Yoona immediately.

"Someone is being clingy~" Sunny teased, causing the kid to blush madly.

"Then I will post it alright? We can't have our fans wondering about a mysterious little kid that appears out of nowhere. Media might cook up weird articles as well, if we don't come up with something before they see you." Taeyeon explained her reason for doing that, and waited for a reply from the kid. Sooyoung hesitated and nodded, agreeing to act as Yoona's little cousin for the time being.

"Why Yoona's though?" Jessica asked.

"As you can see, she's clinging to Yoona right now." Taeyeon clicked the post button as she answered, slightly hinting about something and the girls, except Yoona, get the hint.

-----

"The responses aren’t bad. In fact, it's very good." Tiffany said as she scrolls through the web page. She could see the fans commenting on how cute the kid is and even hope to see the kid soon.

"Stop treating me like a kid!" Sooyoung frowns when the girls tried to play with her like they play with Kyungsan that time.

"It's hard to do that, since you look like one now." Hyoyeon replied, rolling a ball towards the kid. Sooyoung crossed her arms angrily and looked around, before running to the girl and settling herself down next to the doe-eye girl who is snacking on some potato chips. "Aww~ tsk tsk."

"You want some?" Yoona offers the potato chips to the kid, who takes it happily and munches on it. It's the only moment that makes the girls think that, 'Okay. It's Sooyoung. Not a kid.'

"What a clingy kid you are." Yuri commented, grinning at the kid.

"W... What? I... I'm supposed to be Y... Yoong's cousin anyway..." Sooyoung stuttered, peeking at the doe-eye girl from the corner of her eyes. The girls chuckled and shook their heads, sighing.

"What a good excuse you have there to stay close to-" Sunny almost said out something that might exposed Sooyoung's true feelings for Yoona, but she stops in time, feeling relieved to realize that Yoona isn't listening to her. In fact, she's playing with the cat ears on the girl's hoodie. Sooyoung seems to be oblivious about that, or maybe she just didn't bother since its Yoona. She carries the kid up suddenly and places her on her lap, continuing to play with the ears.

"Yoong..." Sooyoung sighed.

"Oh. Sorry... I forget about it... Since you're so small and cute." Yoona sticks her tongue out as she removes her hands from Sooyoung's head but soon, she's fiddling with the tail. Sooyoung sighed and didn't bother about it anymore.

"Time to bathe, kid." Taeyeon informed.

"Okay..." Sooyoung jumps off from Yoona's lap and runs into the bathroom, calling out for the latter soon after because she couldn't reach the soap and shampoo on the shelf.

"She's really intending to cling to you for this one month, Yoona." Tiffany smirks, when the doe-eye girl came out from the bathroom.

"It's alright, I guess... She's a kid now after all and it's kind of cute." Yoona smiles brightly. All of them here, except for Tiffany who’s awkward with kids, love kids after all.

"I bet she will jumping in joy if she hears you saying that." Jessica commented.

"Why?" Yoona asked, not understanding why.

"Nothing."

Yoona shrugs and sits back down on the floor, picking up the potato chips and realizing that it's empty now. Sighing, she puts it down and lies down on the floor, feeling a little tired.

"Go and sleep if you're tired, Yoona. We have a schedule tomorrow morning too." Taeyeon said, getting up and stretching her body.

"Okay..." Yoona got up, yawning. She returned to her room, with Yuri following behind her and they closed the door, getting into their own bed. The rest got back to their own room one by one, except for Taeyeon who is waiting for the kid to come out from the bathroom.

"Where's Yoong?" Sooyoung asked, coming out in a pink pajamas that has a lot of deer head printed on it.

"Time to sleep. Come on." Taeyeon carried the kid up and turned of the lights, heading to the room that Sooyoung shares with Jessica and put the kid down on her bed. "Goodnight, kid."

"Stop calling me a kid! I'm not a kid!"

"Whatever. Goodnight." Taeyeon covers the girl with the blanket and walks out of the room, back to her own. After lying in bed for fifteen minutes, Sooyoung hops down from her bed and heads out, to Yoona's and Yuri's room.

"Yoong...?" She nudges the doe-eye girl gently.

"Unnie?" The doe-eye girl who is about to fall asleep sits up and stares at the kid standing beside her bed.

"I... I... I kind... kind of... Erm... Can't sleep..." Sooyoung scratches her head, blushing slightly.

"You're acting like a real kid now, clinging to her mother." Yoona giggles, patting the girl and carrying her onto the bed. "Araso. Sleep here, little cousin."

"Goodnight, unnie." Sooyoung grins and the doe-eye girl smacks her gently on her small shoulder, before putting the Rilakkuma plush at one side and lying down beside the kid. Sooyoung stares intensely at the sleeping face of the doe-eye girl, blushing madly and thinking that maybe it's a bad idea to come over to sleep beside Yoona. But her tired body tells her that it needs a rest right now and she shouldn't move anymore. Sighing, she closes her eyes and soon, she's in her dreamland.

-----

"Shh... Just look at her. Using this opportunity to get closer to Yoona." Yuri smirks as she points to the kid who is in the doe-eye girl's embrace as the two are sleeping. All the girls except for the ice princess are here after Yuri called them over, and chuckled.

"Sooyoung is going to explode of happiness and embarrassment when she wakes up." Hyoyeon points out. The head of the kid is currently pressing against the chest of the doe-eye girl, in the middle to be more exact, since the doe-eye girl is hugging her like she's hugging Rilakkuma. Wanting to make fun of the kid, Yuri tip-toes towards the bed of the doe-eye girl and pokes the kid, trying to wake the kid up.

"What...?" Sooyoung stirred slightly, turning her head finding it suffocating suddenly. She turns back quickly to catch her breath, her face red as tomato when she realizes that her head is pressed in the middle of Yoona's chest. "... A... A... A little help here...?"

"Enjoying yourself, aren't you?" Yuri smirks, pulling the kid out from Yoona's embrace and waking the girl up in the process. "Time to wake up anyway, Yoona."

"Oh... Everyone's awake...?" Yoona rubs her eyes sleepily

"Except Sica."

"I know. It's expected." Yoona yawned and stretched her body forward, before getting off her bed. Without knowing what's going on before she woke up, she walks out of the room and heads straight for the bathroom to wash up.

"So, how do you feel now? You like being a kid right now, don't you?" Sunny teased the blushing kid.

"W... W... Why would I? I... It's so troublesome... And inconvenient." Sooyoung stuttered, getting away from Yuri's hold and running to the bathroom to wash up as well.

…..

"She's so charming..." The kid's eyes shine brightly as she watches her fellow members perform on stage. She forgets about the embarrassment she felt after putting on the pink hoodie with tiger stripes and tail. At least this time, there aren't any ears on the hood. Her eyes followed a certain member closely, and smiled to herself unknowingly.

"Aww~ she's so cute~" Just then, a group of girls came over and one of them carried the kid up. It's Kara and the one holding her is Nicole. "I heard she's Yoona unnie's cousin."

"I... I want to watch Yoong unnie~" Sooyoung blushed slightly as she did her aegyo, causing Kara to squeal. They sat down and Nicole settles the kid down on her lap, allowing Sooyoung to continue watching. Soon, the performance ended and the eight girls came down from the stage. Sooyoung jumps off Nicole's lap immediately and runs to the doe-eye girl, stretching her hands up to ask the girl to carry her.

"She's clingy huh?" Gyuri asked, grinning at the cuteness of the clingy kid. Yoona gives the an awkward smile as she carries Sooyoung.

"She chooses who to cling. She doesn't like us at all." Taeyeon ruffles Sooyoung's hair playfully, and the latter scowled at her. "See?"

"That's so cuteee~" And Sooyoung ended up having to play around like a real kid.

…..

Probably because of her small body, the tall girl becomes tired easily. After playing around like a kid with Kara, she is now sleeping soundly in the doe-eye girl's arms. In her hands, is part of the doe-eye girl's shirt. It's as though she's afraid that the girl will run away while she's asleep.

"Even though she keeps saying that she's not a kid, she can't help but to behave like a kid in that body." The short leader sighed, as she looks at the kid.

…..
