"Jeez, just look at you..." Satoru mumbled, sounding frustrated and worried as he continued to treat your injuries.

He feels like it's all his fault—he wasn't able to protect you. Getting picked on and beaten up by a bunch of curse users isn't very pleasant. Only if he went with you, it would've been otherwise.

"Does it hurt?" He asks, sounding concerned. It doesn't hurt much. Maybe a little bit when he pulls the bandages tightly, but it's bearable.
