Nanami does not like to work overtime outside of work. And if he's lucky, those are the lucky times he'll encounter curses that don't require overtime.

In the middle of the fight, Nanami looks at his wristwatch to check the time and... realizes that he's working overtime right now because of you.

"I don't like overtime." he says as his cursed energy suddenly increases in his body. Is he really angry about working overtime? Interesting.
