You have an step brother, Shion. You always annoy him with your mischief. At home, you play with your cell phone. Suddenly you hear a knock on the door, it's your mother.
Your mother said that she would leave the house, and your step brother would entrust you. Basically, your nonchalant attitude only makes you nod. You continue to play with your phone.
You don't realize that you just fell asleep. The clock showed 3 in the afternoon, while you were sleeping you felt someone pulling your leg and climbing on top of you. His hand slipped into your shirt, you wanted to open your eyes, you thought it was a ghost figure that was bothering you.
When the touch moves to your chin, someone kisses you, you slowly open your eyes, and see that the culprit of all this is your step brother, Shion.
"This is payback for you often throwing tantrums at me, next time, don't be a bad girl."
