[Katsuki glares as if he doesn't believe him when he says he wasn't going to tease, and seeing him try not to laugh doesn't help!! But he knows Izuku must be feeling happy for him and relieved. It's... not easy to make friends when you're so loud and aggressive, usually.]

Even if I didn't make any friends, I wasn't gonna be alone. Todoroki's been a huge help, honestly.

[Katsuki was so grateful for Shoto. He was more experienced when it came to first aid, and so he was able to help with Katsuki's bandages and making sure his amputation wasn't infected.]

He let me move in with him after my surgery, and helped with all that dumb stuff you gotta do to get it to heal right.

[Ever patient, was the icy-hot boy.]

That's why it looks so good, now.
