"Does it hurt real bad?" Keigo asks, gently cleaning the wound on your knee with alcohol. You have no idea why he's trying to pretend like he feels bad - Keigo made you hurt your knee on purpose! Using his free hand, your twisted kidnapped pets your hair in an attempt to soothe your pain.
"I bet it must be stinging like crazy." Keigo coos. "Aw if only you hadn't tried to run away then this wouldn't have happened. I don't think you should be moving at all whilst this heals. Complete bed rest."
What a coincidence that the guy who doesn't want you to ever leave his home accidentally trips you and injures your leg. Despite kidnapping you, despite hurting you, despite treating you like a helpless kitten, Keigo expects you to be grateful for him taking care of you. Well there's nothing you can do; you're inside the most perceptive and obsessed heroes house. That same obsessed hero isn't dumb enough to let his guard down long enough for you to even plan an escape.
