After days, day by day Yerin really do her plan to teasing Sowon. It's hard time for Sowon, luckily it's still not their promotion time yet, they still on break time to prepare their next album, so public won't see how bad Sowon's flustered by Yerin. But actually it's even more hard for Sowon because while they at their own places (dorm and practise room), together all day, everyday, Yerin's teasing is lot more worst, as if she not having a break, that girl keep on 'train' her unnie savagely. After time to time the other 4 younger girls aware of the issue, at the beginning they thought it was funny and also laugh at it, but then they start to worry and pity for their leader unnie. They want to help, but how?... they just can't figure it out yet...

Sowon is flop down sitting on the floor on the corner of their practise room, they on the middle of their dance practise time. Sowon is panting and drenching in sweat, but not from the dance practise but because she had to ran away from Yerin. That doll-like-girl is really so into her excitement on teasing her unnie, she keep on glued on Sowon all the time, bewilder the oldest unnie. Sowon's heart burst everytime Yerin , she thought that she almost get insane, her body even tremble uncontrollably everytime Yerin come closer always with mischievous smirk plastered on her face and overloaded aegyo. Yerin had up grade her aegyo and it bring even more worst impact for Sowon.

"Stop it, Unnie! Can't you see Sowon Unnie is already exhausted." SinB try to block Yerin's way, preventing that girl to get closer to Sowon.

Yerin giggling, "Hahaha!! It's so fun, SinB-ah. You should consider to make over your visual, make Sowon Unnie fall in love to you too, then you'll know how fun this is. Hahaha!!"

"No! I won't do anything purposely just for torture Sowon Unnie like that. You're being mean, Yerin Unnie. Stop it for goodness's sake!" SinB scold sternly with frown in her forehead. "Let her have a rest. Don't come closer to her to tease again! If I see you purposely do that again, then we --- me and the rest of members --- won't just let you. If necessary we gonna KICK you away from Sowon Unnie, LITERALLY! Don't think we won't dare.. 'cause we definitely dare to do that to you eventhough you are our unnie." Then SinB leave Yerin to pick a bottle of water then bring it to Sowon that greatfully accept it then quickly gulp the water.

"Thank you, SinB-ah..." Sowon express her gratitude while still try to catch her breath.

"We will protect you, Unnie. Don't worry." Umji soothing while wipe Sowon's sweat and tidying her oldest unnie's messy hair strands that stucked on her face because the sweat then tucked it behind her ear.

They just finish their dance practise when Yerin came out from one of the toilet chambers at the time Sowon just enter the toilet room. The red-hair-girl jolted as soon as she see the blonde-hair-girl. No one of other members are there. Suddenly Sowon feeling unsecure and she start to trembeling, she gulp hardly, in her mind that time is there's only a major command to run away, but her body is freezing unable to move.

Yerin clearly can see it. She give her gentle smile, "Unnie, it's okay... I won't tease you. I realize I've been overacting to you. I'm sorry. I've been thought about it and I got conclusion that if I keep on this play and make you uncomfortable everytime I'm near you, then it gonna be my loss. I'm suddenly had thought that what if you can't get over this on forward? then I'm the one who definitely gonna regret it for the rest of my life if It turns that I can't be near you, Unnie... that thought scares me... a lot."

Then Yerin come closer to Sowon, carefully take her unnie's hand and hold it.

"Unnie, I'm sorry. I'm so sorry... I want to be with you comfortably as long as I can. For the rest of our life let's be friends, let's be sisters, forever... I love you Unnie. Will you forgive me?" Yerin carefully said it all that while look straight into Sowon's eyes.

Sowon feel her tremble were already gone, she feel no more nervous, her heart is beating steadily and warm. She realize at that time she can look at Yerin comfortably like she used to be before this girl in front of her change her hair became blonde. No more crazy fluttering.

Ooh.. actually she still the same person.

How I get that insane feel before? It's weird... did I actually weirder than Yuna?

Uhmm... I don't think so..

It's like I suddenly get disease and now I'm heal.

Huft... thanks God.

Sowon is busy with her own thought when finally she feel Yerin squeezing her hands and call her name for several time...

"Unnie... Sowon Unnie... Are you okay? Are you feel sick? Did I annoying you?" Yerin ask in worry.

Sowon can clearly see the worry look from Yerin's face and her sincere voice. Sowon bloom a soft smile, "I'm okay, Yerin-ah. I just finally get through it. I just heal from starstruck. Yerinstruck, actually..." Sowon confess with rolled eyes at her last sentence that make Yerin chuckle.

"Really? You okay now?" Yerin confirm.

Sowon nod, "Yes. I absolutely fine now." She said firmly.

"Aww~... then I can't tease you like before anymore?" Yerin ask innocently can't hide her dissapoint tone.

Sowon glare, "NO! You said you sorry...?!"

"Ouwh yeah... you right." Yerin grinning.

"Yah!! You not really sorry do you?" Sowon ask upsetly, but Yerin just wider her grin. "Yah! You impudent girl!" Sowon pull away her hand from Yerin's grip then smack the younger girl's arm upsetly.

"Ouch!" Yerin groan, "I'm sorry, Unnie. I'm really sorry. But I just can't help to feel sad losing my 'toy'..."

Sowon's eyes bug out in anger, "TOY??!!" Her voice up roaring like a majestic thunderbolt.

"Oops..." Yerin mouthpalm herself and feel shrunk. She got a hunch that she gonna get into trouble in about a moment...

Ouwh... I should educate my tongue and put a brake on it so it won't out of control next time.

But it's too late...

"YERIN-AAAH!!! COME HERE YOU RASCAL!! YOU GOTTA LET UNNIE BEAT YOU UP AND TEACH YOU A LESSON!!" Sowon's anger voice roaring to the entire building.

"Unnie, I'm sorry!! Please forgive me!! Don't hit me! Pleaseee... !! Sowon Unnie, let me pass, just this time. I'm sorry! My Pretty Unnie, just forgive me, please! I won't do that anymore! I'll be obidient to you. I love you!! Sorry!!" Yerin pleading while running away from Sowon's mad chase also dodging from the stuffs that Sowon's throw to her.

"Hey... am I dreaming? Or is there something wrong with my eyes? I just saw Sowon Unnie chasing Yerin Unnie... wasn't she almost faint everytime Yerin Unnie come closer? Or... instead that was a dream? Uhmmm... Is it me too weird or am I turn to insane?" Yuju confusingly scratch her unitchy head.

"No, Yuna-yah. You are not dreaming, Dear. What just you saw was real. You definitely not insane but indeed you kinda weird... sometimes." Eunha said soothingly while caress her roommate head dearly. Yuju nod her head in dumbfounding, while maknaes laughing their heart out at how weird all their Unnies are.

"They all are so unpredictable. We not gonna bored with them." Umji said among her laugh.

"Yeah! We are so lucky being with them. I love this group." SinB said too among her laugh while rolling on the floor.

"Yeah! I agree with you. I love this group. I love these people! Hahaha!!" Umji said again while clapping uncontrollably.
