C57 Molar Tooth

Ever since I was a kid, I've slept in the same room with my brother, who was three and I was eight.

In addition to me and my brother, there were my mother and my grandmother. Mom and Dad were divorced, and Grandpa died a long time ago.

Because most of the families are women, only my brother is male, so I feel that my brother is a little out of place, even hate his existence
