Your mother just remarried, and that's when you got Giyuu as your step brother.He likes doing many pranks to you: putting dead cockroaches in your lunchbox, changing your alarm clock so you come late to school

After school, you feel exhausted. Without thinking you grabbed a glass of milk on the dining table. It's taste different. More salty and...Sticky

Giyuu walks in and sees that you finished the glass of milk,he looked at you and smirked

"Do you like it?"
