"arasoo let's make it success, i will be in chaeyoung side and nayeon will be on sana side, we need to make them believe it and try as hard as you can to be natural so they dont suspicious us"
"arasoo"

After that we go back to class and act like nothing happen, and jihyo unnie know about this too, the one that didn't know is chaeyoung, sana unnie and dahyun, i don't know why but all of them say that we shouldn't tell dubu, and i just do what they said

*a week later*

Sana pov 

*What happen between tzuyu and mina, why mina being so close with chaeng, argg, but wait shouldn't i happy?? But no no no i can't be selfish anymore, and seriously mina why chaengie?? And why i worried about chaeng and mina together, it's not like i like chaeng or mina right? No no no of course no you pabo sana yaa* i said in my mind cause i have been wondering why mina and chaeyoung being so close

Chaeyoung pov

*Lately mina unnie being so close to me, I'm really happy, yeah I'm but why i feel something wrong when I'm watching sana unnie and tzuyu together, it's feel something unease in my heart, am i jealous? Is this jealousy but for who?*

After several week i getting tired seeing those two always together, i need someone to talk about it, but who? Ahh my no jam bro, so i came to her room

*knock knock kncok*
"yeahh" jungyeon unnie open the door
"anyeong broo"
"anyeong, it's so rare to see you here, what make you came here?"
"yeah i have something i want to talk about"
"about what?"
"sana unnie and tzuyu" am i see something wrong cause i see little smirk in her corner lips
"owhh araso, come in"
"arasoo"

So i come in and i tell her about everything and the confused situation i have, and she told be

"just follow your heart, don't rejected it, the more you reject it the more it make you confused, now tell me when you see mina and tzuyu together are you feel the same"
"yeah i feel the same but not anymore"
"then you know the answer chaengie, i know you know, you just don't want to accept it, please accept it and be honest "
"but, seriously sana unnie? It's really funny you know"
"no chaeng it's not funny, I'm being serious now and i just want to tell you i hope you didn't late when you start realize it"
"hehehehe, arasoo, gumawo unnie, don't be to serious and i have to go now it's getting late, byee"

I keep thinking about what jungyeon unnie said *hope you didn't late when you realize it* that word keep ringing in my head ughh i hate this feeling

And week by week sana unnie and tzuyu getting more closer and closer, i can't take it anymore, now i admit it that I'm jealous, that i fall for that clumsy unnie. I'm really at my limit until i see sana unnie sit on the bench while her head leaning on tzuyu, i came straight forward to her, i grab her wrist and take her to the back of the school, we left tzuyu dumbfounded and i don't really know what to do and why i grab her wrist and take her here

"chaeyoung~aaa why?? Why you grab my wrist and take me here? Is there something wrong?"
"yeah there is something wrong"
"what's wrong?"
"you sana unnie"
"me? Huh? What i did wrong?"
"you shouldn't getting closer to tzuyu"
"why? She my favorite dongsaeng"
"she is mina unnie girlfriend, sana unnie, you shouldn't do that, mina unnie is your friend"
"of course I'm not going to do that chaeng i think you got misunderstood tzuyu and i only have unnie dongsaeng relationship "
"are you being serious now? And you being honest right?"
"yeah I'm chaeng beside i don't love tzuyu anymore, i love someone else" i could see blush on her cheek, guess I'm late AGAIN, why my love life so hard
"ow..hh good for you, and hope you luck with that person" i said 

And i start go away, i don't want to hear who that person cause i know that's not me, i go away without turning back cause i don't want sana unnie to look at my pain face
