My dear teacher ( YANDERE sana X reader)

The real daughter

Sana "What the fuck are you saying"

Momo "Nayeon we'll leave for a second"

Sana drags Momo out of her apartment, and back into theirs

Sana "Why did you stop me"

Momo " You need to tell her you love nayeon"

Sana " and I do not"

Momo " She wouldn't bother you and y/n much because she'd weird out around you"

Sana "You are not wrong but I can't stand that girl at all"

*phone rings*

sana "Hello father? I already sent you the files what happened?"

father "I wanted to invite you for a family dinner tonight dear"

sana "Stop with these tricks, I'll leave your company either way"

Father "My real daughter has returned, i want you to meet her and guide her, that's the least you could do for me"

sana "What do you want me to do? teach her how to snap people's necks?"

father "Have a talk you both are sisters, it could be a little fun family dinner"

Sana "Fine, a little fun last family dinner okay Dad?"

Father "Tonight at 9 pm, I'll text you the venue"

*end the call*, back at your apartment, you were quite confused about what happened

y/n "Wait a second? sana is leaving her job for you? what?"

nayeon "I know right I'm not even that admirable "

y/n "She promised me she would be a better person. and she is trying to be a better person for me." y/n seems to be lost in her thoughts, nayeon tries to shake her off

y/n " huh? oh sorry"

nayeon "Oh by the way, are we chill?"

y/n "Not yet, you have to treat me"

nayeon smiles "Okay you bet"

Sana and momo return to your apartment, and sana tries to make a painfully awkward confession

Sana " It's true nayeon I love you"

Y/n yelp in shock  "ehh??? "

Sana " But I'm willing to move on"

nayeon " Ah.. Okay? "

Sana " So help me move on from you"

nayeon " What? What am I supposed to do??? "

Sana " Just stay as far as possible from me I cannot stand your face for a single second"

nayeon " Wait was that supposed to be insult?"

Momo " Uh nayeon, Sana is bad with words Don't mind her"

*phone rings*

Nayeon " Oh it's jeongyeon hey y/n I'm going for a sundae wanna join? "

Y/n " No I'm good " Nayeon nods with a weak smile and leaves the apartment, as soon as she step out.

Sana cuddles up with y/n tightly,
Sana" I missed you so much y/n!! "
Sana kisses her on the cheek and caress her car crash wounds

Y/n " Are you not upset on me for running away? "

Sana "I missed you too much to be angry on you, just let me hug you for a while ok?"

Momo "cringe go get a room"

Y/n "this is my room"

Momo "fine I'm gonna head out"

Sana lays down beside you, while you were still immersed in her arms, you slowly blurt out

Y/n " I missed you too. "

Sana " I promise y/n I'll never leave after this"

y/n " Are you really quitting your job Sana? and why did you say you love nayeon"

Sana " Yes i quit killing people now and now nayeon wouldn't bother us anymore"

Sana " Now sleep! You must be tired"

y/n " I'm not"

Sana " Fine then I'll leave "

y/n " Ah no don't, fine I'll take a nap"

Felt asleep in her warm embrace, she was right you were really tired.

Tzuyu " Dad where is your step daughter? "

Dad " Um she'd be arriving any minute"

Sana rushes into the huge fancy restaurant, their dad waves her hello, she approaches them and takes a seat.

Tzuyu " Miss Sana you?? "

Sana " Tzuyu??? "

Both the girls were shocked to reunite in such a weird way, the dad seems happy to have them sit together.

Dad " Seems like you both already know each other"

Dad " Sana she is my real daughter soon to be my company owner Tzuyu"

Dad " Tzuyu she is my adopted daughter sana, her works are the greatest one in my company"

Sana looked at Tzuyu with dead eyes, as if she is ready to kill her. . ..
