Todoroki's never been one for being soft, so the fact he's soft toward you says a lot, you're his one and only soft spot and he's accidentally admitted the fact to Midoriya before- he's also not one for knocking, he does on the odd occasion, but not now, he knows something is up with you, he knows you'll hide it if he knocks, so today, he took a deep breath and opened the door full speed, shutting it behind him, freezing a little upon seeing your sniffles and tear lined face look up at him also frozen before he slowly approaches like you would approach a skittish cat

"Why are you upset?" He asks, you hear a hint of concern even through his stoic face and blunt tone
