Sana and Tzuyu are on the back seat, both sitting near the window.
Their father looks at the rearview mirror, and noticed them.
"Did you guys fight again?" The man asked
The girls at the back flinch at the same time "No" they answer in unison
Their Mom look back "You're both grown up now, I know there are things that you don't like about each other... But please, don't fight"
Usually, Sana and Tzuyu will argue, and blame one another whenever their parents talk to them about siblings fight. But this time, they just nod, and agree to their mother.
Their parents are driving them to University. Their father which is Tzuyu's biological Dad, and their Mom, Sana's biological mother, loves to send them to school every morning before they head to the office.
When their parents dropped them on the University's gate, Tzuyu and Sana remained silent.
"Uhm... I'll go this way" Tzuyu awkwardly utter, and point at the west part
Sana nodded "Okay"
"Should we go home together?" Tzuyu asked
Sana lift her head and face the latter "Ye-yeah sure... If our professor dismiss us early, I'll go to your building"
"Okay unnie" Tzuyu replied with a smile
Sana smiled as well, this is the bond that they lost when they got busy with school works. Thought they fight all the time, they're still close.
~~
Tzuyu's first period ended, their next class for the day will be in one and a half hour.
Right now, Chaeyoung and Tzuyu are together, and were sitting on the bench on the rooftop.
Chaeyoung noticed that Tzuyu's not in herself, the latter end up telling her about what happened last night.
"It's fine... Just no penetration, or else you'll break the rule" Chaeyoung
"What rule?" Tzuyu asked in confusion
"The siblings rule" Chaeyoung
"Where the hell did you learn that?" Tzuyu
"Dad said, the reason why I have this thing unlike the others" Chaeyoung points at her crotch "Is because I'm here to multiply"
"Yah!" Tzuyu hissed
"What?" Chaeyoung asked, innocently "We're special, that's what Dad called us... there's reason why we have a penis in this body... But I'm telling you, there are rules"
"Have you ever tried it?" Tzuyu suddenly asked
"Tried what?" Chaeyoung
"Doing it" Tzuyu
Chaeyoung's eyebrows furrowed "Doing what?"
Tzuyu look around before speaking "Sex" she whispered
Chaeyoung shook her head "Nah... Just masturbate"
"You speak like you're used to it" Tzuyu
"What do you expect? I'm a teenager" Chaeyoung pat Tzuyu's arm "But I'm curious"
"Do you think we should start dating a girl?" Tzuyu
"Of course... But what if they found out that we're different? They might runaway"
Tzuyu couldn't say a word. She do understand the latter, that's also the reason why she never dated someone. She's afraid, just like Chaeyoung...
That people won't accept them, and the worst part is what if the person they love, won't love them back because they're different.

Mina was checking her phone when Jihyo peek on her side.
"You're really a sweet sister to Chaeyoung, you even use your picture as lock screen wallpaper" Jihyo giggles
"Chaeyoung's a sweet kid, she's obedient too" Mina replied "Anyway, are you done with the drawing assignment?"
"About that, I'm not good at arts... So no..." Jihyo
"But we have to pass that tomorrow" Mina
"Our professor extend the due date for me... I'll be representing our department for the quiz bee..." Jihyo
Mina sighs "Good for you... I haven't started mine..."
"You have an artist sister, you don't have to worry" Jihyo
"I actually feel sorry for her... She was loaded with school projects lately, it's really hard to wake her in the morning these days..." Mina
Jihyo chuckles "She's always online every night, I don't think she's busy"
"Playing is her stress reliever" Mina defends Chaeyoung
"Whatever" Jihyo then turned to Sana
Their class ended earlier as expected, Sana was putting some of her books inside her bag when her Jihyo and Mina approaced her.
"Why are you in a hurry?" Mina asked
"I'll fetch Tzuyu, we'll go home together" Sana replied
Jihyo chuckles "You're still babying your sister... You and Mina are alike"
"Well she's my younger sister, so she's still a baby" Sana
"Sana unnie" Jihyo smile sheepishly at the latter
Sana put on her bag "Why?"
"Can I date Tzuyu?" Jihyo asked
Sana's eyes widened "WHAT!?" She exclaimed.
"Keep it down" Mina tried to calm the latter
"Yah! Jihyo- yah! Are you out of your mind?" Sana
"No, that's why I'm asking for permission, because she's your sister" Jihyo
"It's a NO" Sana disagree "Tzuyu's still a baby... Dad told us that we can't have a boyfriend until we finish school"
"Then a girlfriend will be fine" Jihyo
Sana knit her eyebrows and point a finger at Jihyo "Stay away from my sister" she then turn her back at the latter.
Sana then leave after that...
"I told you, don't mess with someone who has elder sister" Mina told Jihyo
"Why can't I date Tzuyu?" Jihyo protest
Mina just laugh "Let's go, the sky looks really dark... I think it's going to rain... I'm going to fetch Chaeyoung, so that we can go home early..."
"Chaeyoung's not a baby, she can go home alone" Jihyo protest, but Mina didn't listen

Sana made her way to Tzuyu's building, she was about to go in when she saw Tzuyu walking out of the architecture building.
"Tzuyu- yah!" Sana called
The latter lift her head and walk to Sana. They then started to walk home.
Sana noticed the latter's mood, Tzuyu's not saying a word since they met after school.
"Tzuyu what's wrong?" Sana worriedly asked
Tzuyu lift her head, and Sana see the loneliness in her eyes "Why am I different?"
Sana was taken aback, she knows that Tzuyu isn't the type who's proud, that is why she always lift the latter's mood, but this one is different "Tzuyu you're not different, you're special"
Despite of what happened to them, Tzuyu's still Sana's younger sister, she still care for the latter.
They are now in the middle of the street, with no one around.
"Being special is still different" Tzuyu
"Did someone bully you?" Sana asked in anger
Tzuyu shook her head "I just thought, I can never be normal with this in me"
Sana take a step near the latter "There's nothing that is not normal with you"
"I can't even date because of this" Tzuyu
Sana's forehead creased "Are you frustrated because you want to date someone?"
"I'm a teenager, kids at my age goes out and enjoy their life" Tzuyu
"You can also do that" Sana
"I don't think so, no one will like me if they found out" Tzuyu
"Hey! You have your friends, you even have us, your family" Sana
Tzuyu pouts and started to walk home "You're just trying to lift me up"
Sana walked beside the latter "Because it's true"
Tzuyu look at the latter "It's hard to believe you"
"And why is that?" Sana
"Because you're a devil" Tzuyu replied and runaway, laughing
"Yah!" Sana yelled and chase after Tzuyu "Come back here!"
~~~
It's raining raining hard outside, the Son family have just finished eating dinner...
Chaeyoung's in her room as usual, she's playing god of war on her phone when Mina came.
"Chaeyoung- ah..." Mina
"Hmmm?" Chaeyoung replied
"Can you draw me a female reproductive organ" Mina asked
"Eh?" Chaeyoung
"I need it for my biology class" Mina
Chaeyoung paused the game she's playing, and face Mina "Yeah sure..."
"I couldn't find ny book, I think I left it at school... Can you just search it online?" Mina
Chaeyoung nodded "Okay"
That's how casual they talk, specially in a serious situation... And when Mina's not in the mood to nag the younger one.
"Do you have bond paper with you? Or should I get some?" Mina
"No need for that, I have some" Chaeyoung replied
Mina smiled and hug the latter "Thank you Chaeyoungie..."
Chaeyoung chuckles "Fine... Just treat me pizza"
Mina let go, and show OK sign "I'll treat you tomorrow"
They were smiling at each other, when the lights suddenly went out.
"Aaaah" Mina immediately hugged Chaeyoung
"Jeeez! It's brownout" Chaeyoung reach for her phone for some light "There's no signal too... "
Mina let go of the latter when Chaeyoung used her phone as flashlight.
"Mina! Chaeyoung!"
The two goes out of the room when they heard their parents call. They peek through the loaf to see their parents on the living room downstairs.
"Are you fine up there?" Their Mom asked
"We're fine Mom" Mina replied
Their Dad came with a lamp "If this heavy rain won't stop, there might not be electricity until tomorrow morning"
"What?!" Mina exclaimed "But I still have assignments to finish"
"There's a heavy rain... You still have class tomorrow?" Mina's mom asked
"There's no thunderstorm, the class won't be suspended" Chaeyoung answered
"Then go to bed, both of you" Chaeyoung's father told them
The two girls nod, and went back to Chaeyoung's room... Mina suddenly sat on the bed and cried over her project... Mina's a straight A student, and if she missed the drawing, then her standing will change... It will be a great loss to her grades...
But there's no way that Chaeyoung can draw her assignment... First is she left her book in her locker, and there's no internet connection because of the heavy rain...
Chaeyoung sighs, seeing her sister cry is one of the view that she never wished to see...
Mina might do strange things that sister shouldn't do, but Mina's a nice sister to her. Too kind and generous as well...
"Unnie.." Chaeyoung approached the latter "What do you think if you'll be my specimen?"
Mina lift ler her, Chaeyoung just gave her hope "Will that be fine to you?" She asked
"It's fine with me, is it fine with you?" Chaeyoung
Mina glance at the door "We should lock the door"
Chaeyoung nod and went to the door to lock it. She then went back to Mina after that...
Mina set up the flashlight, while Chaeyoung took her art materials...
Mina remove her pajama and underwear, then sat on the edge of the bed... She closed her eyes as she spread her legs.
Chaeyoung chuckles, seeing how shy Mina is... Despite of being a tease stepsister, Mina's still a quiet and elegant girl...
Chaeyoung sat on the floor, she's in front of Mina, just right in front of the latter's folds... She then started to draw the latter, but something pop on her mind.
"Unnie, I can't see it well... Open it" Chaeyoung
Though Mina's shy, she used her index and middle finger to move her pussy's lips to each other's side. Showing it more to Chaeyoung...
Chaeyoung smirked, Mina's showing herself to her, with her eyes close... And she finds it sexy...
"This will be a long night" Chaeyoung told herself
