[ as much as kaneki appreciates the worry - it's very kind of you, Izuku - he doesn't know how to answer that because every answer will sound terrible.

"Someone impaled me with their tentacle" or "I was thrown around like a ragdoll and then knocked unconscious" don't seem to be appropriate answers to give a stranger, so kaneki is not going to do that.

instead, he is going to lie even though he isn't particularly good at it ]

I'm sure! I'm sorry I worried you, I arrived all healed up. [ kaneki pats himself. he doesn't flinch, there is no pain since there is no wound. ]

I got hurt when working at the coffee shop, it wasn't that bad anyway... [ somewhat!! ]
