His dad and Haruchiyo moved in last week; He is your stepbrother. You are incapable of accepting both the existence of your stepbrother and the fact that your mother is dating someone else.

One day as you were getting ready to take a shower, Haruchiyo suddenly emerged from the bathroom wearing a towel around his waist and with wet hair and a wet body. There is calm on his face. When he turned to face you, he grinned.

"Oh, hey, sweetie" he said, pinching your cheek.
