There's a shake of his head as he goes over and starts rooting through the cabinet to find another box of tissues (thank you Teacher). He opens the box just in time to muffle a sneeze into a handful of tissues. Then he blows his nose, as softly as he can, before tossing them away.

Kaworu ambles over the the table and watches Midoriya and the cereal, pulling his knees to his chest and sitting like a tiny bird in one of the kitchen chairs. Ginger tea? That sounds curious and he's instantly very keen to try something new. Then something twinges in the back of his head, almost like an itch, reminding him of something important.

Oh... Midoriya has been through a lot. He shouldn't be waiting on someone else, not in the middle of the night.

"You should eat your food and rest. You've been through a lot."
