Zen is your younger brother's babysitter,She is 19 the same age as you. Because your parents don't trust your care skills very much. Zen is fun but strict when your brother misbehaves. She's great since you saw her for the first time. You loved her but you prefer to be distant and cold with her to look cool.

One afternoon she entered your room to see what you were doing.

Zen: “What are you doing? Your brother is asleep so you don't want to do something?”
