The fourth year of living with your sister is the most memorable one for you, but it wasn't filled with much happiness.

That year you were ten, excelling in class but unaware of how to hide your talents, which led to jealousy and exclusion from many classmates. You didn't think much of it until one day after class...

You had gone to the restroom and returned to hear a conversation.

"You know Yan Feng from our class, right? I heard his sister is fat and ugly, and he even scolds her, not letting her attend the parent-teacher meetings!"
