15 years ago, 

10 years old Eunha is crying at the corner of corridor outside her classroom. All her classmates are already out for having their lunch at the canteen already but she choose to crying there alone

Eunha buried her face on both of her knees, hugging tight her legs into her arms. Nobody know why she's crying since she's a newcomer to that school. She just enroll to that this morning, she's still awkward with people surround her

Even though she's Korean but she was born in Japan. She's facing her growth time at Japan, there's not many difference from Korea to Japan but still, Eunha can't fix herself there really well

"Yea! It doesn't tasty at all" Eunha lifting her head when she heard a group of girls are chatting about food quality that sell at their school canteen 

"Maybe that auntie forgot to put a salt in our lunch" Eunha didn't care about that girls was walks toward her 

"If following my heart, I've burn that canteen already"

"Woah, calm down Yerin. If you burn that canteen where are we gonna eat?"

"Argh, do I care? I'm hungry. I didn't take my breakfast this morning just because I want to eat at here" that girl named Yerin said out of frustrated 

The second tall girl from that three girls decided to said more but stop when her eyes caught a figure that was sitting while hugging her knees tightly. She can't see that girl face since that latter was putting her head on her knees 

"Hey, hey. Who's that?" She ask her two friends, make both of them stop bickering for awhile 

"Where? Hurm, Sowon. Do you know her?" Yerin nudging Sowon arm 

"Hmm, if I'm not mistake. That's Jung Eunbi, new student. The one who get into our class this morning" Sowon, the tallest girl said 

"We have new student?" Yuju and Yerin ask in unison 

"Yea, if you guys didn't slept in class awhile ago. You'll know about her" Sowon rolled her eyes 

Without answering Sowon words, Yuju make her way slowly toward Eunha. Yerin and Sowon just shrugging before following her step

"Hi" Yuju sit next to Eunha on the floor, but Eunha didn't bother to answer her warm greet 

"Hey, you're Jung Eunbi right?" Sowon ask gently before following Yuju action 

"Yah! Are you deaf? We're greeting you nicely, so please respect it newcomer!" Yerin getting inpatient when both of her friends warm greet just got ignore 

"Yerin, calm down will you. I know you're hungry but don't scold her, she's getting scare" Yuju scold her 

"It's ok, let me handle about her. You talk to this Eunbi girl. Now, come here you" Sowon said as she slung her arm around Yerin neck before pull that girl to somewhere, she just ignoring Yerin cry voice who is begging her to stop 

Yuju just chuckling seeing her friends antic. She's turning her head back to the figure in front her. Slowly she put her hand on Eunha shoulder 

"Eunbi? Why are you crying?" Yuju ask gently "Did you hungry?" Eunha just shaking her head "No? Uhm, is there's someone bullying you?" Eunha shaking her head again 

Yuju scratching her head, dont know what else to do. She's taking out her handkerchief then take Eunha hand before put that handkerchief in that short girl hand

"I don't know how to make you stop crying but I think this handkerchief can help your knees from getting wet. Stop crying for too long, you'll lost your energy. We still have a few class after this, we need energy. But it's a different story if you're planning to get sleep. You'll regain your energy back" Yuju was laughing to her own words but stop when Eunha just giving her a plain look 

"Uhm, I heard my friends call for me. I'll going now" Yuju get up then run, nowhere 

Eunha just look at her antic before stare the handkerchief in her hand. She then chuckling when she remember Yuju excuse about her friends are calling. She sure enough that she didn't hear a thing since just now 

That's how their friendship starts. Eunha try to getting closer to Yuju and her friends, it's happen when three of them are welcoming her into their group with openly arms. Eunha is cute, kind and smart. So it's not like three if them are mind about her to be one of member to their unofficial group 

Day has turn to week and week turn to years. Four of them are still being a close friends. Eunha is more closer to Yuju than to Yerin or Sowon. She's so comfortable with Yuju. Yuju treated her well, she's a full of patience type of person. That's what make Eunha comfortable telling all her problem to that latter 

"Yuju" Eunha lay next to Yuju on that taller girl bed

"Hmm?" Yuju give a quick glance on Eunha before turning her attention back to her game

"What will you do if I said, I'm gonna leave?" Yuju immediately look at Eunha, she saw that girl use such as uneasy expression

"Where did you wanna go?" Yuju frown, she somehow don't want Eunha to leave. Not after she has slowly develop a feeling to that girl 

"My mother sickness is getting worse. If there something happen, I have to go to Japan. And live at there" Eunha pouting a bit, she don't want to tell Korea, her school, her friends and Yuju of course 

"Eunha ah, don't leave. Please" Yuju holding Eunha hand softly 

"I'll try to talk to my father" Eunha patting Yuju hand

"You must. If he didn't allow you to stay here, I'll give him a call and talk to him" Eunha chuckling 

"Wow, you want me to stay that much?" 

"Of course, I can't alive without you" Yuju pouting make Eunha pinch her pout 

"Such a sweet talker. But if I stay, how can I pay a visit my mother?"

"I can handle it, I'll ask my grandpa to preparing the flight for you to Japan" Yuju said seriously 

"Yuju ah" Eunha chuckling, Yuju is too cute "You don't have to do that. Why you want to do it by the way?"

"It's because I love you. You're my friend, I don't want my friend leaving me. I'll be lonely" Yuju said sadly 

"You still have Yerin and Sowon" Eunha try to pursue Yuju for let her go, even though she didn't want to leave either 

"But they aren't you" Yuju hug Eunha tightly. Her action make Eunha let out her heavy breath, she softly patting Yuju back 

"Ok, I'm not gonna leave" Yuju lift her face up with brightening expression 

"Promise?" Yuju held out her pinky swear

"Promise" Eunha connecting her pinky swear with Yuju's 

They're in Yuju room for completing their homework. After has done with their home works, Yuju decided to play her favourite game and Eunha just followed her lying on the bed

"Eunha, promise me again. You're not gonna leave me"

"I promise Yuju ah, I promise" 

They make a promise without knowing that one of them gonna break it due to forces. Without knowing that one of them will having a heartbreaking due to the another one leave

End of Flashback. 

"I'm sorry for breaking our promise Yuju. I'm in dilemma on that time. Dilemma between my love to my mother and my love to you" Eunha softly touch Yuju picture that they took on their school trip about ten years ago 

She's trailing her finger slowly and calmly along Yuju features. There's nothing different from old Yuju and Yuju in this time. Yuju still has her hair bang, her eyes still black shining like before. Her smile of course, it's still attractive and addictive

"You're just the same Yuju ah. There's no different or change about you from past till now. That's my love for you, no difference or change. It's still the same" Eunha smile softly to that picture

Umji smile cheekyly when she's accidently hearing her sister words. She passed by Eunha office room by an accident when she want to take some water from the kitchen and saw there's light in her sister office room 

"Oh, so Eunha unnie love Yuju unnie? Hurm, gotta tell SinB about this" Umji whisper excitedly before quickly run away before got caught by her sister
