This is satzu x hyunjin (+2jin), you can skip this if you want. I just couldn't help but to write a story about tzuyu and hyujin (from loona) since they really look a like and have a lot of similarities.

trigger warning: mentioning suicide

a/n: this is quiet long...I'm now making a new satzu one shot for those who wouldn't want to read this and also stan loona.

Ms. Myeong, a woman who's in her late 20's was invited by her friend who recently opened a new theme park. Only a few people got invited and luckily (not really) both of her daughter's bestfriend was also invited making them jumped in joy. Exactly. It was supposed to be a joyful day for them but unfortunately both of her daughter wouldn't allow that making her glare at them.

"Why are you fighting again!?" she yelled in frustration, not liking to see this scene again for the 5th time of the day.

"Tzuyu already won a lot of games just for Sana Unnie! It's my time to win the games for Heejinnie!" The 8 year old girl protested as she points her tiny index finger on her sister.

The woman squints her eyes as she look at the child "It's Tzuyu Unnie for you, Kim Hyunjin."

"But Eomma–"

"No buts! We've already talked about this Kim Hyunjin. You are going to call Tzuyu as 'Tzuyu Unnie' since she's older than you–"

"But she's only one year older than me!"

"EXACTLY! She's one year older than you! that's why you should call her Unnie!" The woman snaps her head to the other kid who looks unbothered. "And as for you Chou Tzuyu! Let your sister win the game. You've already given Sana a lot of stuff toys from those claw machines and mini games, isn't that enough?"

The older child shrugs "It's not my fault that I'm good with games and Sana Unnie was the one who kept dragging me to win those prizes for her. Hyunjin just really at playing."

With Tzuyu having a blunt personality, the sisters starts to fight again while their step mom sighed in frustration.

Can someone tell me why did I decided to adopt these two kids again?  The woman asks herself as she look at the two girls shouting at each other's faces.

As if on cue, flashback of memories suddenly played in her mind on how she took care of both kids while they were still infants. Tzuyu's mom died in the process of giving birth while Hyunjin's mom ran away, leaving both babies to the hands of their irresponsible father, in the end, he ran away. She hates him to the guts for leaving Tzuyu and Hyunjin but she was also thankful for him, if he didn't left the two girls, she wouldn't have two beautiful angels right now.

Said angels are now grabbing each other's hair.

Remembering those tragic yet beautiful memories, she couldn't help but to smile while watching her kids grabbing each other's hair.

"Mama! I'm going out! I'll be heading to Sana Unnie's house!" 17 year old Tzuyu shouts as she hurriedly go down the stairs to put her sneakers on. 

Her mother went out from the kitchen, apron wrapping her body as she holds a spatula in one of her hands "Before you go to your bestfriend's house, wait for me to finish the lunch that I've been preparing for your sister." She ordered and used the spatula to point the half empty lunchbox in the dining table.

Tzuyu groans "Hyunjin can it up. Besides, Sana Unnie and the others are waiting for me." The latter said as she kneels down to fix the knot of her sneakers, only to fall down on the floor when her mother threw a pillow at her, perfectly aiming her head.

"Bring this lunchbox to Hyunjin or you're grounded for the whole month." Before Tzuyu can protest, her mother already went back to the kitchen, leaving her daughter whine in the living room.

Tzuyu rolls her eyes as she fetch her phone from her pocket to text Sana.

weirdo but the loml <3

hey baby  

i'm gonna be late 

mama wants me to bring hyunjin's lunch for her stupid football practice

can u wait for me? 

Afraid to tarnish the perfect daughter image in her mother's eyes, she decided to keep it from their mother that she's dating a girl, not just any girl but Sana. Their mother have high expectations for them ever since she was a kid. Being also the oldest and the most responsible one between her and Hyunjin, her Mama always thought of her as the perfect oldest daughter (calling names and bullying her younger sister isn't included), she can always see how proud their mother whenever she's introducing them to her friends, always bringing up the topic on how she exhilarated from her supposed to be grade level to Sana's grade level, how responsible big sister she is, and how both of her daughters topping in the class.

She even brags that someday both of her daughters will marry a very handsome and successful man, but Tzuyu doesn't want that. She wants Sana and she knew there's a possibility that her mother might disapproved. She was the typical asian mother after all.

Her train of thoughts suddenly stop when her phone vibrates, a message from Sana.

weirdo but the loml <3

okay my giant aegi (ﾉ´ з ')ノ

just be careful on your way and always remember that your pretty cute japanese girlfriend is waiting for you σ(≧ε≦σ) ♡

She cringed at her girlfriend's reply but the smile on her face says another thing, she's inlove indeed, smiling as she stares at Sana's message. She might not yet have the urge to tell her Mama that's she dating a girl but she's sure that Sana is the only one that she wants to be with.

As soon as their mother gave her Hyunjin's lunchbox she kissed her cheeks a goodbye and quickly went out. She can't wait to see Sana.

Fifteen minutes of walking and she have finally arrived in their school. She immediately went to the school's field, eager to give the lunchbox to her stupid sister so that she can see her girlfriend already but only to frown when she saw no football players playing or having their daily training, in short, there's no sign of her stupid sister.

Tzuyu rolls her eyes, looks like her sister is having her basketball training instead. It was a fact in their school that she and her sister are very athletic. Hyunjin being good with football and basketball, while Tzuyu being the ace player in both the archery team and volleyball team. The whole school also knew that this two beauties are half sisters. Both of them couldn't deny it since they really look like each other.

A few students stares at her as she pass by in the hallway but the latter just ignored it and goes straight to the gymnasium. Her stupid sister is making her walk for minutes and refraining her to get some cuddles time with her japanese girlfriend. When she finally reached the entrance door in the gymnasium, she hastily opened the hollow metal door, ready to shout at her sister but stopped when she only saw two girls kissing each other.

"What the–"

She didn't expect this kind of scene when she entered the gymnasium and she definitely did not expect her younger sister to have a make out session when she's only 16. Well most people lost their ity at 15 she thought.

"Unnie!? I– H-Heejin and I– w-were just–"

It was the first time she heard Hyunjin calling her 'Unnie' but she couldn't stop herself from laughing.

Hyunjin's face is all red, the expression on her face made it more funnier for Tzuyu.

"You look so ugly when you blush" Tzuyu comments and starts to laugh more. Tzuyu knew she should be surprised, the fact that her sister is also gay (like her), and using her respective sport as an excuse just to make out with her childhood bestfriend, but she couldn't help but to laugh when she saw her sister's surprised ugly face.

"Anyways" Tzuyu breaths after laughing for several minutes "I won't tell Mama since I also have a girlfriend who's actually waiting for me now but–" she throws the lunchbox at Hyunjin's face which the younger catched before hitting her (good thing she's in the basketball team) " you for making me walk just to see you getting smooches from Heejin." she rolled her eyes before exiting the gymnasium.

"She's so annoying" Hyunjin scoffs and rolls her eyes. But deep inside, she felt relieved when her sister laughed at her face first, the last thing she wanted is Tzuyu never accepting her. They may fight a lot of times, screaming at each other's face a LOT of times, bullying each other, playing pranks (to the point were they almost got grounded for a one whole year), but their bond as sisters is much stronger than their relationship with their mother.

"Hyunjin? Why are you crying?" A younger Tzuyu asked when she saw her sister crying while sitting at the corner of the room, she thought her sister went home already since their school is just beside their home but instead she found her crying when she pass by her classroom.

"Go away" The younger girl sniffles, not looking at Tzuyu. She was only seating on the floor, her legs folded close to her body as she use her knees to lean her arms, burying her face there, refraining from anyone who wants to see her face.

Tzuyu frowned, she was about to protest but stopped when she notice her sister's legs. It was full of dirt and red marks, Hyunjin's head was buried on her arms but her forehead was still visible and Tzuyu saw a lump. She reached her sister immediately and forcefully pry away her arms to see her face.

Hyunjin was about to shout at her sister when she did that but stopped when Tzuyu spoke.

"Who did this?" Her older sister seriously asked. It was the first time she saw how serious her sister is.

"Who did this?" Tzuyu repeatedly asked when her younger sister didn't reply, she only lean down to hide her face from Tzuyu but her older sister held her chin and made her look in the eyes.

"Hyunjin, who did this?" For the first time in Hyunjin's life, she was afraid of her sister. She was used to them bickering a lot, making a lot of noise and do unnecessary things at each other.

"N-No one" She nervously answered.

"Don't lie to me."

The way her sister say it is like spitting a venom, it was enough to make Hyunjin cry and tell the truth.

"I-It was J-Jackson and s-some other kids that I don't k-know."

Hyunjin just cried again and but stopped when she felt a tight grip on her arms.

"Come with me." Her older sister said and dragged Hyunjin outside of the classroom. Hyunjin didn't protest and just followed her, not knowing what to do.

When they've finally arrived in the playground at the back of the school, Tzuyu immediately went to Jackson who was playing with some other kids. Sana even called her but she was too furious to notice her. 

When she reached the back of Jackson, she let go her sister's arm and harshly pushed him on the ground making him fell, face hitting first but Tzuyu didn't care. Jackson turns around, getting angry who pushed him before he can even react Tzuyu already beats him to it. 

"Wha–"

"Did you do this to my sister?" Tzuyu asked, pointing her fingers at the crying Hyunjin who's only beside her.

"Yes, bec–" Before Jackson can finish his sentences, Tzuyu harshly step his foot making him cry out of pain. But she didn't care, she was mad.

She leaned down to grab his collar and made sure they were looking at each other's eyes "Listen to me you punk, I am the only one who's allowed to make my sister cry, and I will be the ONLY person who's allowed to bully her, do you understand me!?" He nodded, getting afraid at Tzuyu. "If I saw my sister crying again because of you and your stupid friends, I won't hesitate to come at you again and kick your balls." She harshly let go of him and walks away, she went to her sister who's still crying but being comforted by Sana and Heejin. She pulled Hyunjin towards her and gave her sister a hug.

"I'm the only person who's allowed to make you cry and if someone made you cry again, I won't hesitate to hurt them."

Their day ended when Tzuyu and Hyunjin got grounded for a whole week. Their mother saw how dirty Hyunjin's skirt and Tzuyu lied for the first time and told that she and Hyunjin played in the playground. Hyunjin slept beside Tzuyu that night, hugging and thanking her for what she did.

"I'm your Unnie, Hyun. No one is allowed to make you cry except me. Not even Mama, she's allowed to make you cry but only a little since we're still young." she whispered before kissing her little sister's forehead. 

Hyunjin smiled at the sudden memory while looking at the fading figure of Tzuyu's back but stopped when she realized what Tzuyu said awhile ago.

"Wait– did she just say she also have a girlfriend? that ." 

—

"Wha?–What the hell?" Tzuyu mumbled when she saw clothes on the floor.

She just got home from school and the first thing she saw was random clothes scattered everywhere around the living room, there were also clothes on the stairs.

She picked up one of the clothes and realized it belongs to her sister. She was about to call her mother or anyone around the house when suddenly she heard a voice coming from upstairs.

"Eomma please! I'm sorry!"

Tzuyu's sure it was Hyunjin's voice, she calmly put back the clothing on the floor and gently walk upstairs. As she slowly walk, deep inside she's nervous, she doesn't know why but her entire system is screaming that something bad is going to happen. Feeling she won't calm down any moment, she stopped right in front of her and Hyunjin's bedroom door and took a breather.

Before she can even exhale, the door in front of her suddenly opens, revealing a messy Hyunjin, her sister's hair was disheveled like someone just pulled her hair, her entire face was red, tears are coming out from her eyes, it was obvious she was crying for hours based from how red her eyes is.

"Hyunjin? Why are you crying?"

"Unnie..."

It's just a one word but it was enough for Tzuyu to pull Hyunjin in her embrace. The younger girl tightly hugs her older sister, it was so tight that Tzuyu can feel Hyunjin's trembling body. From her peripheral vision, she can feel their mother's eyes staring at them, a frown was visible on her face, she looks really angry in Tzuyu's eyes. 

Before Tzuyu can even ask a question, their mother already spoke.

"Get out of my house, Hyunjin."

"Mama? What's happening? Why are you so angr–"

"BECAUSE THAT FREAK IS NO LONGER MY DAUGHTER! I CANNOT ACCEPT THAT SHE'S DATING A GIRL AND WORSE SHE'S GAY–"

"So what?"

Their mother was taken a back on the way how Tzuyu talks back to her. She never expected this kind of attitude from her oldest daughter. She frowned, getting more angrier than she was, her piercing gaze bore to the direction of her daughters, she took a step closer to them wanting to slap their faces. Tzuyu move her sister on her back sensing their mother's furious, using
