You turned on the light to your room and found Bakugou standing in the middle of your dorm.
"Are you psychotic?! Why are you standing in my room in the dark?" you tried to keep your voice down.
He completely ignored your question, he yanked you into your room, closing the door behind you. "Did you go on a date with dunce face?" He looked at you intently, not letting go of your arm.
You tried to get your arm back, but his grip was too strong, "I asked you a question first, and what does it matter to you?"
"I came here to talk with you, or did you not get my text?" He bit the last part out at you. Knowing that you chose to ignore his message. "And it doesn't matter, I just-" he stopped, he didn't have an answer for that last question, at least not one that wouldn't admit how he felt about you.
There was a pause he looked away from you for a moment. When he glanced back all he said was, "So, you did go out with him." He stated it, like it was already a known fact. His eyes glaring, not at anything in particular, but like he was upset just at the thought of it.
You let out a breath you didn't know you were holding and came clean. You didn't know why you did but it just felt like the right thing to do. "We went to the movies; I didn't really even want to go. I just used him, so I didn't have to talk to you. But you can see how well that plan went." You couldn't meet his eyes as you said the last part.
The silence filled the space between you, settling in as you stood still, his hand still wrapped around your arm. Both of you didn't know what to say at that point. Part of you wanted to kick him out of your room, you couldn't help but still feel upset about today. But another part of you just wanted to get this talk over with. You were tired of not knowing why he was so upset.
So, you broke the silence first. "You came here to talk, so tell me, what happened today with Shinso?"
You could see his jaw tighten as he clenched his teeth, he paused a moment before he answered, "Next question."
"Just answer the question."
With his jaw still set he almost growled, "I said next question."
With a sigh you spoke again, "Fine," you took a breath, calming yourself down, before you asked another question, "Do you really think I'm that kind of person? Someone who's just messing around with-" but you didn't want to finish your sentence. You looked up into his eyes, they weren't glaring into you anymore but there was still something there, blocking you from seeing how he truly felt.
He closed his eyes, like he was contemplating his answer. "No, I don't. I was upset and angry and I said something that I didn't mean." He didn't look at you as he spoke, like he didn't want to see your reaction to the confession that he was wrong.
"Why did you get so mad?"
His jaw clenched again, and his shoulders and arms became tense. You couldn't help but notice that they looked more defined somehow and your mind drifted slightly wanting to know how good it would feel to have them wrapped around you. You scolded yourself mentally, now was not the time for that.
"I don't know," he sounded annoyed, "I just can't help getting upset sometimes when other guys are around." He groaned like he didn't want to admit that. "When I heard that dunce face say he wanted to take you out and then I saw you with Shinso, I just got angry and it's not like you've made any move to tell me or even show me how you feel." He began rambling, rushing through his words. "Even now, I can't help but get upset knowing that you looked that pretty on a date with that dunce face loser."
