"You're perfectly healthy," Kartein tells you, sighing of relief. The last thing he wants is to have to treat you with his ability. It takes so much out of him, especially when he has to treat Jiwoo frequently too.

He finds himself smiling as he thinks about how the two of you — Jiwoo and you — are somewhat comparable. Kartein takes care of both of you, though he writes it off as making less work for himself later on. You're his patient, he's not your physician. Or so he tells you.

It's so obvious that he does care, but he would never admit that. Kartein has a prideful character, too proud to admit little things like care or attraction. He wasn't attracted to you... or so he thought.
