Katsuki was bound to notice at some point. And he did.

They were laying there on Katsuki’s bed watching Pacific Rim. One of their favorite movies to watch together. They would talk about what would have happened if they were the ones drifted in Gypsy. If there would even be Jaegers if Kaijus were a thing in the current world. How the pro heroes would handle it. How they would handle it.

But this time Katsuki noticed that Izuku wasn’t as excited about the movie as he normally is. He’s been noticing this alot lately. How Izuku just gets in his head.

It seemed odd to him because he knew Izuku better than anyone. When Izuku cares about something he is passionate. And bold. He cares about being a hero. So he’s bold when it comes to challenges in this area. But Izuku isn't like that around Katsuki. At least not any more. He seems out of it. More than once has he caught Izuku muttering about it, but the words were intelligible. So he decided to finally say something about it, after all these days, he paused the movie.

“Hey.” He tried to catch Izukus attention. But the boy didn't notice. “Hey, Izuku.”

Izuku looked towards Katsuki. “Yes Kacchan?”

“Is something wrong?” Katsuki spoke softly. Something he didn't do often. “You’ve been acting weird lately. You’re not sleeping either, I can tell. Something is on your mind. And if it’s about me. If I’m not like you thought I’d be, you don't have to stay, I understand. I know I don't deserve you-”

“Kacchan!” Izuku exclaimed, “No! I love you. That hasn't changed. I made the first move, don't forget that. I wouldn't have done that if I didn’t want you. I just- there’s been something on my mind. And I just don’t really know how to tell you, even though I know I should.”

“You can tell me anything.” Katsuki cringed at how cheesy he sounded.

“I know Kacchan.”

“So then do it. I want to know. And even you just said you probably should tell me.

Izuku sighed. He knew katsuki was right.

“Okay.” Izuku stated bluntly.

They both sat up and faced each other, closing the laptop sitting on the bed.

“But-” he continued, “You have to promise me. You won’t say anything until I am finished speaking. Not a word. Because this is really important.”

Katsuki was about to protest when Izuku interjected. “Please.” he begged.

The blonde boy just growled, “Fine.”

“Thank you.” Izuku fidgeted a little bit, trying to figure out how to word this in the most gentle way possible.

“Spit it out”

Katsuki sighed and motioned for Izuku to hurry the fuck up.

“Todoroki likes me.” Izuku spoke and as Katsuki realized what he said he opened his mouth to speak but Izuku beat him to it. “But he likes you too.”

That stopped Katsuki in his tracks. He was about to talk when Izuku reminded him, “You promised.”

Katsuki nodded.

“I walked past his dorm one morning and overheard him talking to Jirou. It was just after everyone found out about us. He was crying. Crying about how he loved you and loved me and now we’re together. He said he’s happy for us, but he was also heart broken.

“I couldn’t stop thinking about it afterwards. I thought about all of the possibilities. He didn't really like us, maybe he was just joking. I tried to convince myself, but I knew. He was sobbing. I could hear the hurt in his voice, Kacchan.

“I thought, ‘No, it isn't possible for someone to like more than one person at a time.’ I thought about this for days. And unconsciously I began watching Todoroki. Analyzing him. How he became more distant from me, and he never really smiled anymore.

“I asked myself, ‘Is it morally right? Thinking about Todoroki this much, when I’m with you?” He heard Katsuki suck in a breath, “I know I love you, that is a fact that hasn't changed since we were kids. And it’s not going to change in the future. But I caught myself noticing new things about Todoroki. How he holds himself, the way his hair falls into his face. Soon I began to notice that I was unconsciously watching him when he was in the room. I spent hours and hours just thinking about all of this. All of this information crammed into my mind, all of these thoughts overwhelming me.

“I spent the nights researching, filling notebook after notebook. And I learned things. I learned about polyamory. Polyamory is being in multiple relationships, with everyone's consent. Like three way relationships. Everyone is okay with it, and often they all end up with the same people.

“In learning this, I came to terms with my attraction and feelings for Todoroki, and his feelings for us. Todoroki doesn’t know I know all of this. And if it’s okay with you. After you process all of this, I would like to approach him about it.” Izuku finally finished. “You can talk now”

Katsuki stayed silent for a moment. “This is what you’ve been thinking about”

Izuku just nodded.

“So, IcyHot likes me, but he also likes you, but you also like him and me. And you want us all to date. But he doesn't know you know.”

“Yes. Kacchan, I love you so much, and if you’re not comfortable with this, I will let it go. We’ve waited so long to be together-”

“No, Izuku. You wouldn't be happy. You like Half n’ Half, that’s something I have to accept now. I can’t force you to be with me.”

“I want to be with you Kacchan.”

“But you also want to be with him. And he wants to be with you.”

“He wants to be with you too,”

“I know, Izuku, you keep saying that. But this is a lot to think about. I can still barely process the fact that you can tolerate me, let alone Icy Hot. Not to mention the fact that he likes you too and I don't know how I feel about that. Izuku, this is a lot to process.”

“I know Kacchan, believe me I know. If you need time-”

“I do. Just give me some time to think about things. I don’t know how I feel yet”

“Okay. Thank you Kacchan. For not blowing up and overreacting about this. Most guys would just break up with me on the spot.”

“Well not me,” Katsuki looked into Izuku’s wide green eyes. “I love you too much for that.”
