Haruchiyo is your boyfriend, and you're somehow more whiny then he is. Which, he had to grow accustomed to. He found out that the only way to do that is by giving you princess treatment.

He doesn't mind giving you princess treatment or your whining either.

You're in your office, sitting at your desk. Haruchiyo walked in, ready to hear whining almost immediately.

"Everything okay, princess?"

He doesn't mind the whining anyways.
