My dear teacher ( YANDERE sana X reader)

The Minatozaki sisters

Momo " Go on y/n read the script why'd you stop? '

y/n " Umm ..... Please come back soon Miss Sana "

My hands were Quivering in fear, is this exactly what I was thinking, Is this place a trap, Sana might have come to kidnap me, Maybe I was overthinking, Suddenly I remembered what nayeon once said to me.

Flashback 

Nayeon "You know this place is my favourite cafe, I used to come here all the time when I was a kid"

y/n "This place really feels so cozy"

It was a Japanese-styled cafe, As nayeon told it really seemed pretty old and classic, They had all those Japanese art on the wall.

Nayeon "Her name is Mina she used to be here when I was young, this place is still running I am surprised  "

y/n "What???? Mina?? nayeon she will kill me! she will kill us please let's go"

Nayeon held my hands and tried to calm me down

Nayeon "Hey look at me, ok? They are not here! they can't reach you, They can't ruin your life anymore, They just can't ok? every time you think of them just remember this, don't let them haunt you ok??"

Flashback Ends

Momo "Please read it again with a little expression "

I must remember that the world does not revolve only around them, I must move forward, I must live on, YOU CAN DO THIS Y/N!

y/n *takes a deep breath* " I will miss you, Sana"

Momo "Well done now you'll have to read it to a person "

y/n "Fine! I'll do it"

 I felt a little confident, I raised my shoulder and told her to call that person, from her looks I could tell she was impressed.

Momo "Hey sis! come out"

From the back glass door, She entered, After a long while, she haven't changed at all, My whole body went numb for a second, Should I cry, Should I run? but Nayeon told me they wouldn't come to me ever again, Am I being delusional?

Sana " I missed you to babe"

y/n "You aren't real! "

Sana "What do you mean?"

She holds my hand which was quivering in fear, They were all sweaty 

Sana " I missed you a lot "

y/n " NOOOOOO you are not real!!! " I pushed her away 

Sana "Don't say that darling "

I ran outside her cabin, crying and whining like a lunatic, Nayeon told me this is fake it was all in my brain, so how could she?

Back in Momo's cabin 

Momo " Sis she is running away won't you catch her "

Sana " Where would she even go? She is already mine don't worry momo"           

She relaxes and sits back on the couch, Momo rolled her eye and gave that annoyed look

Momo " You and your overconfidence "  

Momo "Well I forgot to tell you, I told our big sister about your arrival"

Sana "Huh? So what ?"

Momo " She says she is coming here to claim her property"

Sana " Her property? around this area? Never knew she had one around here, Well anyways I don't care, I just came here to get my y/n back"

Mina, Sana and Momo were sisters, Momo was the youngest, Sana was the middle child and Mina was the oldest, Momo was an obedient kid she always listened to her parents and her two elder sisters. Momo was taking her parent's business company forward, whereas Sana and Mina had almost cut off all ties with their parents.

Back at the apartment 

It was still raining, heavily, I somehow reached my house, locked the door, closed the curtains, I picked up the phone kept it on my bed and immediately called Nayeon.

Nayeon "Hello? y/n? everything alright?"

y/n " Noo *cries* She..she came back she was in the audition, Nayeon help me!! *cries*"

Nayeon "y/n remember it's all in your brain right? I am real she is not ok?"

y/n "But I just-"

Nayeon "No but's y/n take your med and go to sleep ok? Please"

y/n "Yeah I am sorry to disturb"

Nayeon "No it's fine, just call me when you wake up"

*ends the call*

They were on the train, and jeongyeon and Wendy gave her those weird looks

Jeongyeon "Seriously? Not even have been few hours?"

Nayeon "See, she gets these mental seizures and delusions very often and she only has me, what if something happens to her "

Jeongyeon "Wait she has a mental condition?"

Nayeon "Yes, she thinks that her teacher will track her down, wants to kidnap her and punish her, All she around is her teachers, I had to force her to see a psychiatrist"

Nayeon " Sometimes she yells at night"

Wendy " What?"

Nayeon " I am a sinner"

Wendy "Shouldn't she be in a mental asylum then?" Wendy says that in a joking way to lift up the mood, but Nayeon was really offended 

Nayeon " Don't say that ok? "

Wendy " Fine sorry"

Jeongyeon " Now brush it off, just enjoy with us"

Back at the apartment

I took my medicines for schizophrenia and turned on the TV, I was watching a romcom, and I forced myself to laugh at the scenes so that I could feel a little less stressed, but suddenly the bell rings, I became really happy because I thought nayeon is back for me, I smiled and yelled.

y/n "Who is it??"

*no reply*

y/n "Nayeon you are back??"

Mina " I have come to claim my property darling"

y/n " Mina....?"

Mina "Now come on be a good girl open up the door"
