All the Years Between us (Yandere! teacher Oikawa x Student! Reader)

11. Heartbreaker

It's a nice sunny Friday, you and Erika skipped school to go shopping. You wanted to get a new book and something cute to wear on an upcoming date with Oikawa. Luckily, your mom didn't catch the two of you, that would have been a nightmare.

You were walking through the streets chatting and laughing with Erika. Out of the corner of your eyes, you spotted none other than your boyfriend sitting at a café with a woman who reached her hand across the table to touch his.

''Oh my god, your name it's Mr. Oikawa, I knew he had a girlfriend! My sister went to college with him and he slept around a lot'' she said way too loud, it caused both of them to turn around and look at you.

You could literally feel your heartbreak and you couldn't even react it would totally expose everything that had been going on between you and him.

''Disgusting'' it was all you could say as you walked away faking a phone call from your mom.

You could feel your phone going crazy with texts and calls. You took one look on your phone and blocked his number. As soon as you got out of view you broke down crying.

Why? What's wrong with me? Am I really that unloveable...

----

It was my day off. I was supposed to meet with Iwazumi but something came up last minute. I was about to go back to my car when I heard a familiar voice call out my name.

Ugh, not her.

I had to fake a smile, I couldn't be rude to her no matter how much I want to, her sister is dating my friend. I had one of my violent urges creep up on me.

''Hey, long time no see'' I said, turning around to walk away to escape the encounter.

''I actually need a favor, would you mind?'' she asked while running up to me.

''I'm going on a date so I don't really have a lot of time'' I lied.

''Tooru, you liar. I know you were supposed to meet with Iwa-chan!'' she huffed.

''You caught me, what is it?''

''Would you escort me to this café, I'm meeting my sister but I have no idea where it is. I'll treat you to an iced coffee''

''Sure, but I won't stay for long'' I said hiding my irritability.

We walked towards the close by café she talked eagerly the whole way. I knew she wasn't over me.

Disgusting, disrespecting y/n like that, she shouldn't act like that even though she doesn't. I keep hinting about her.

We entered the café and sat down. She ordered the drinks and carried them over. I want to finish this as quickly as possible. I have to check up on y/n otherwise I'll go insane.

She flirts with me non-stop, I want to puke, I thought.

She moved her hand on top of mine and that's when I heard it.

''Oh my god, y/n, it's Mr. Oikawa, I knew he had a girlfriend! My sister went to college with him and she said he slept around a lot!''

I looked out the window meeting y/n's eyes, she looked horrified. I could feel my heart sink. It isn't what it looks like but I can't stand being the one to hurt her.

She looks me deep in the eyes and read her lips muttering disgusting. She takes out her phone, says something to her friend, and walks away. I jumped from my seat and walked to my car. I spammed her phone in pure desperation.

Pick up, pick up, pick up, PICK UP!

Then it happened, she blocks my number. I feel my sanity fading away, pure chaotic violent thoughts roamed my mind. I heard a knock on my window and was greeted with her disgusting face.

''Tooru, what's wrong?'' she said.

I got out of my car and violently pushed her to the ground only to pull her up by her collar. She yelled in pain and told me to let go.

''If you ever come near me or hurt her again, I'll tie you up and pour acid down your fucking throat. Do you understand, you filthy whore?'' I hissed in her ear.

''Y-yes, just let me go! I won't tell anyone, I promise!'' she cried.

I let her go and spit her in the face. I got into my car driving to y/n's house. I need to prove my love and explain, I don't want to use forceful methods on her. I have to explain it to her.
