Osaka - Japan, May 6th, 1924

A girl with brown hair is holding another girl in her arms, they are on the grass, the blood of the small girl is starting to running down and getting mixed with the mud. “You know I'm not leaving you right ? “ the girl in the other's arms said almost like a sighed, like her last breathing.

But Sana couldn't lose her, not now that she just got her back, it wasn't fair, she was young, they were young and got a lot to live. “Dahyun...I want to believe in you,but…” Sana tried to hold Dahyun tight but was afraid of hurting the girl she loved so much, she took one last peek on her heart, a place so pure and warm but someone had to put an arrow in there, just because they were in love with each other, just because their happiness bother them so much.

“I'm sorry Sana, I love you”. And just like that the younger gave her last breath, in the arms of the woman she promise that would never leave.

Seoul - Korea, March, 7th, 2018

“Hurry up we're gonna be late” Sana was getting by the kitchen she heard Jihyo yelling to her. “Why were you being so loud this time at the morning?” Jihyo looked at her and just smile, a beautiful one by the way. Sana's been living with Jihyo since she got here, they also share the little house with Momo and Mina, two japanese friends Sana made some years ago, while trying to fix some problems of her past. Since them, they never got away from each other. It's been a while since Sana haven't make any contact with people, she just prefers to be on her own, but the trio always find a way the embrace her on their madness or in they hug group.

The four girls were already in the car, Jihyo was driving, Sana was on her side and the other two girls were at the back of the car. "What are you thinking of ?” Sana turned back and saw Mina with a clothe too elegant and rich for a first day in the school. “Nothing… It's just I've got a feeling about this year” Momo put her head on Mina's lap and star playing with her glasses trying to clean them. “I have a feeling about this year too” Mina took her friend's glasses and starting cleaning up for her, she was going to say something but the driver was faster. “Mind to tell us?” Jihyo said more like an order so the japanese stood up and said “It feels like our life's gonna change”.

As soon as they got into the school Jihyo went to class with Momo while Sana and Mina stayed on they classroom. “You need to fix this thing” Jihyo said while giving Momo little taps on her back. “I know, maybe one day I'll do it” Momo sighed as she tried to fix her glasses.

Jihyo was already in her class and Momo was trying hard to get in hers without tripping or breaking anything “Mrs Hirai so good you're here” The japanese turned around just to see the secretary talking to her with a girl on her side. The girl was very pretty, white skin reminded Momo a tofu, oh how she misses eating a tofu, it's been a while actually since she had any fo- “So, can you do that Mrs Hirai ?’ She looked to the old woman and said yes, whatever it was it couldn't be a bad thing. “Thank you Mrs Hirai, now go to your class you can't be late”. As Momo start walking the tofu girl walk by her side, she was about to say something but the girl was the one to start the conversation. “I hope you don't mind showing me the school, you must got things to do so it's okay if you don't want to, you know ? “. This is what the secretary was talking about, it all makes sense now. “That's okay, let's start again, my name is Hirai Momo. What's yours ?”. With a big smile the girl said. “Kim Dahyun”.

Jihyo and Mina was having their lunch and talking about random things when they saw a girl sitting alone at the table beside them, the girl was really pretty, brown hair, looked a little shy, probably not Korean, Jihyo wondered why she was alone she seems a nice person to go around with. “Stop staring” the korean girl looked at Mina and saw a little smile. “I wasn't… Just wondering why she is there alone”. Mina look at the girl and understood the concern of her friend, the girl really seem to be alone not because she wanted but because she doesn't have anyone. “Hey, wanna sit with us?” Mina stood up from her sit and went ask her, it wouldn't kill her just ask. “Errm...yes s-sure”. She sat with them, but was too shy to start a conversation so Jihyo was the one to open . “So, are you a new student ?” The girl looked at her and nod. “What's your name ?” Mina was the one now who got the girl's attention.”Tzuyu” she shyly said and looked down to her plate. “Good, well I'm Jihyo and this is Mina”. Tzuyu nod again and stayed quiet, she wanted to say something she really did, but the girls was too afraid to say something wrong, to reveal herself. She couldn't to this, she have made a promised.

The first day at the school was almost finishing and Sana, Mina and Jihyo was at the parking lot waiting for Momo. “We've made a new friend today, she's shy but I bet it's because is her first day” Jihyo said that with a big smile, her hopes on the brunette was high, she did expected them to become real friends. “Oh my gosh you don't know how much I've missed you” Momo showed up out of nowhere and hugged Mina's back like it was the only thing she could do. “You were the one who was missed the whole day Momoring, where were you ?” Mina said that turning her friend to face her. “I've made a new friend, come here” she reach for Dahyun’s hands “Hi, my name is Kim Dahyun”. The girls all greeted her saying their names, except for Sana that froze the moment she saw the girl, she was so alike the woman she loved once and forever, she couldn't say anything, she couldn't feel anything. Suddenly their eyes met and she didn't know what to do, she was paralyzed if she could define herself right now she would be a rock. “Hey where's your manners ? Tell her your name” Sana got out of the transe as soon as Momo talked to her. “S-Sana, my name is Sana”.
