After Kirishima and I try to go along with the best excuse we could think of, Kacchan eventually starts to walk away. Though not before declaring that he'll soon find out the truth from me, which will most likely happen. He starts to leave, but before he can get that far I call out to him. He turns back to me with an aggravated look on his face, so I decide to cut right to the chase.
    "I do want to talk to you about something later." I tell him. Almost instantly, Kacchan turns around, ignoring what I said. Shocking me at how careless he can be.
    "Wha-? Kacchan! I'm serious. It's really important." I yell to him. He continues to walk, though after a moment or so I hear him speak again.
    "Sure, just don't waste too much of my damn time." He says. My heart skips a beat, happy at the fact that he actually said yes. I get excited, hoping that when we talk I'll find out what's going on in Kacchan's mind. My thoughts are interrupted when Kirishima suddenly throws his arm onto my shoulder.
    "So Midoriya..." He says as he leads me back into my dorm. When the door closes, he starts to speak again.
    "You must've had it rough, huh?" He says.
    "Yeah, thanks for saving me. How did you know I needed help though?" I ask him. Kirishima then proceeds to take his phone out of his pocket.
    "I figured something happened, so I thought I'd head over here just in case." He tells me as he shows me the messages from the group chat. Apparently when I tried to hide the messages from Kacchan earlier, I accidentally sent some random text messages to them. Completely dumbfounded, I put my head down and rub the back of my head, getting all embarrassed about it.
    "Ahh. I see..." I say. Then I let out a sigh in relief, knowing that in the end those accidental messages helped me in the long run. Kirishima starts to laugh at my reaction then tries to change the subject.
    "So about the party. We were thinking of getting a custom cake for him that has a bunch of flavors, since everyone has different preferences."
    "Oh! That sounds nice. Is everyone gonna contribute money for it?" I ask.
We continue talking about our plans and texting the chat for a little while. Though while he's texting the chat, I decide to let Kacchan know when I'd like to talk to him. I write that if he's available tomorrow, we can talk after school. Surprisingly, he answers pretty quickly. He texts back:

Kacchan:
Idiot. Just head over here when you're finished with your damn study buddies.

    This left me more shocked than I already was. I let him know that I'll be there soon, growing more anxious by the minute. He texts me back saying that the door will be unlocked when I get there. I blush a little bit, it's just so unexpected. To think that'd he'd ever act this way with me. Then again, it seems like Kacchan is full of surprises lately. After chatting with Kirishima for a little longer, he goes back to his dorm room. While getting ready, I let Kacchan know that I'm heading to his room. Walking down the hall, I start to get worried about what might happen.
    "It's amazing how cooperative Kacchan is being with me of all people. Maybe he's is just playing a trick on me and will leave the door locked. Though considering the circumstances Kacchan doesn't seem like he'd do something like that, it's not his style. Furthermore..." I mumble to myself. I continue to mutter this way as I walk to the elevator thinking of all the possibilities of what could happen to me today. I press the number four button on the machine, and the doors slowly close. I remain quiet, wondering about what I want to say to him. 'Should I confess first, or ask for the real reason he kissed me?Surely it can just be because he wanted to force me to tell him the truth. Could he really like me? Maybe he's just using me, that seems more like it.' I think to myself. Suddenly I remember to check my messages for Kacchan's response, but there's no reply when I look. I get worried again, wondering if this truly is just another way for Kacchan to mess with me. Taking my chances, I get off the elevator and continue my way to his room. As I get to the front of his door, I instinctively try to knock, then remember that he said he'd leave it unlocked for me. I slowly go for the knob, hoping it won't be locked. Luckily enough, it wasn't, and a sigh of relief escapes my body. I walk into the room and lock the door behind me to show that I'm not running away from this, no matter how nervous I may be. As I'm getting to the end of the hall, I start to call out his name.
    "Kaccha- Huh!?" I say out loud, reacting to the sight of him sleeping on his bed! My head drops, upset yet happy that I was over thinking this for nothing.
    "Seriously.." I say to myself. I lift my head back up and look at Kacchan. My body relaxes as I look at his handsome face, though my heart starts to ache.
    "I really want to know what you're thinking." I say quietly. I sit next to him on the edge of the bed, admiring the gentle expression on his face. I start to slowly rub his head, amazed at how soft his hair is. 'Should I wake him up? Probably not, he gets grumpy when he wakes up. Besides, this is probably the only opportunity I have to do this.' I think to myself.
    "You really are cruel Kacchan, doing all these things to me. Making my mind a big mess..." I whisper. Bringing my hand to the side of his face, I begin using my thumb to rub his cheek.
    "I wish things were better between us, I wish I could figure out why you do the things you do. I just.." My thumb then starts to lightly touch his lower lip, and I blush as he reacts by making a light and small moan. 'I need to stop.' I think to myself. 'I need to stop before things get out of hand, but I just..' I lean towards him, and before I knew it my lips were against Kacchan's. They felt so soft and warm, making my body heat up. I press my lips a little harder onto his, almost unable to hold back everything to want to do to him. After a bit, I release our kiss and lick his lips. I raise my head up to see his face flushed into a deep red. I narrow my eyes at him as I grip the sheets. Putting my face next to his, I gently press our cheeks together.
    "I-I love you Kacchan." I say, slightly wishing he could hear me.
    "Is that right?" I hear him whisper into my ear. My mind begins to panic. 'I'm so dead!!'
