It is an extremely normal thing to say to the guy who broke his bones on purpose multiple times. Someone has got to join Kaworu in scar solidarity if they haven't already. Midoriya sets his spoon down. Kaworu is... glad. Midoriya doesn't know or care if it's a platitude. He'll make it true.

"That doesn't mean you should. Anyway," he says, rising and padding in his socks over to the boiling kettle demanding attention, "I hope this will make you feel better."

He retrieves a jar of ginger honey syrup he brought over for this specific purpose and stirs some into a mug of hot water. He slides this over to Kaworu ("Careful, it's hot.") and returns to his cereal.

"Thank you for having me over even after all that. It's probably for the best that I'm not spending a lot of time at home." He chews his Cap'n Trench thoughtfully.
