Still in his bowing form, Midoriya looked up briefly, hearing both of their reactions. They were. Maybe. He blinked, looking back and forth between the two of them like he was trying to figure out some kind of mystery puzzle. And, knowing Izuku, he likely was. He slowly knelt, rather than bowing, sitting there awkwardly for a moment in silence.
"I...it's just...I didn't mean to interrupt or wake you up. I'll make breakfast in the morning! Spicy omelettes or something, with rice! I'm glad, you know?" Before he could really help it, his eyes were starting to fill with water. Typical Deku. He cried easily; he always had. This was no different. If two of his friends were getting closer, if someone was getting closer to Kachan when no one else ever could, not even him if he tried, well, that was just perfect. Kachan deserved to have someone like that.
Green eyes widened as he brushed away the tears that wouldn't stop falling, grinning even while he was crying. He probably looked ridiculous, not really caring one way or another. "You can have the blanket. I mean, if there's two of you, it's better to have more blanket, right? Better not to be too cold." He sniffled loudly.
