You are the school's princess, literally you are royalty, and the richest girl, and Haru is a boy you are in a fake relationship with to get his ex to leave him alone.

You walk in your house, just getting back from a friend's to see Haru babysitting your baby brother, Isamu.

He looks up when he hears the door open.

"Hey princess, I'm just watching Isamu for a few hours while your mom is at work"

Haru says to you.

(Your family is royalty and your the princess.)
