My dear teacher ( YANDERE sana X reader)

should I stay or should I go?

Flashback

An year before Sana joined in as a teacher, y/n had a massive crush on tzuyu. The topper and mean girl of the class, people didn't like her being so straightforward.

y/n was engraving tzuyu's name on the last bench, when teacher was teaching, chaeyoung smacks her on the head.

y/n " yah what"

chaeyoung " you are interrupting our pen fight, fuck out"

dahyun " this is cringe, why don't you just tell her"

y/n " do you even remember what happened when a guy proposed ?"

chaeyoung " what?"

y/n " she told him, if he didn't leave at that instant she'll break the flowerpot on his head"

dahyun " ouch"

chaeyoung " you are a girl, maybe she'll go easy on you"

dahyun smirks " maybe instead of flowerpot, she'll throw flowers on you"

chaeyoung " nah flowerpot seems more reasonable here"

y/n " i got an idea!, I will silently place a love letter in her locker, and she'll never know who it was"

chaeyoung " you gonna get caught dude"

y/n " im witty and smart, i can never get caught"

y/n spent the whole night writting that letter, and as soon as she passes the letter in, someone taps on her shoulder.

tzuyu " did you put in a letter?"

y/n " um yes, it's not mine tho, a guy in my class likes you so he sent me in"

Tzuyu " can you tell me who's it"

y/n " he's too shy sorry I can't"

Tzuyu " I don't take in letters from the coward, if he likes me tell him to say it on my face"

She politely hands the letter back.

y/n " ok wait"

Tzuyu " what?"

y/n " please read it, he likes you too much"

Tzuyu " y/n I'd read it right away, if you tell me who it is?"

y/n " taehyung!"

tzuyu " He's gay "

oh shit i forgot...i was panicking i didn't knew what to do, so i spilled it out....

y/n " I wrote it"

tzuyu " meet me after school" she takes the letter and walks back into class

I told everything to dahyun and chaeyoung and they were just making fun of me, but i felt anxious, what if she makes nuisance out of this. i don't like her friends, they are too bitchy and mean, especially jennie.

tzuyu " sorry if i kept you waiting"

y/n " not at all " I waited an hour to get rejected, so pathetic of me.

tzuyu warmly smiles " the letter was pretty cute"

y/n " you liked it?"

tzuyu " yea but why'd you lie?"

y/n " i was afraid that you'd throw a flowerpot on my head"

she laughs out " oh y/n you're so silly ", I realized this is the first time i was seeing her laugh out loud.

tzuyu " I'm thinking that we could be something" she smiles at me

y/n " what??"

tzuyu " take a hint god" she smacks your shoulder playfully, and writes her number on your palm.
