The Real World (Oikawa Tooru x Reader)

Cheating

After the longest chat of my life time about what we should do for a project, we left the classroom. "Hey let's have eachother's phone numbers so we can text each other about the project?" Oikawa smiled while putting his hands on back of his head. I glanced and Reji and I was on the edge of saying 'how about we don't do that you motherfucking prick' but Reji knew me too well. So he gave me the look "keep your cool" which I did. So we exchanged phone numbers and made a group chat.
The same day me and Reji started walking to a little ice cream shop that was few blocks away from our college. "Hey did you ever think that you are maybe...a little too tough on Tooru~Senpai?" "Pffffffffttttt sense when did you two start to be on first name basis? Are you a couple~~? OoooOo" I could see rage in Reji's eyes, so I turned away from him and tried to giggle as quiet as possible. "SHUT UP IM JUST SAYING DUMBASS! Hmph." "Awww fineee I didn't mean to offend you...that much..."
"WOW JUST....WOWWWWWW (NAME)"
"Okay Okay Fine!" I said while still trying to compress your giggles together. "Maybe I am too harsh on him, I mean it was a long time ago so..." I said truthfully. I actually thought about it a lot of times...if I was going too harsh on him. But more rumors I hear about him dating someone. The more I think it's for the better to be so cold towards him. People may call it jealousy, but I just like to call it forcing yourself to hate someone. Kuroo knew from day one that I would never get over Tooru, but he still took me under his wing and always protected me no matter what.
"I might give him another chance, but Kuroo will not like it...like at all" I told Reji while looking at my turned off phone in my hand. I got to my house and said bye to Reji. It took a while for me to find my keys, but when I opened the door I started hearing. Wait? Moaning? Your eyes were ready to let the tears roll down your cheeks while you slowly started taking the stairs to the bedroom. There should be an explanation...r-right?

I was standing in front of the bedroom door, hearing loud moans. My tears were already flowing down my cheeks while I looked up at the ceiling. 'How could he....?' was the only thing I thought. I opened the door instantly after thinking of how should I storm off on Kuroo. But when I opened the door...

"N-no...how dare you?"
