I'm in the book, but I'm not a character in the book.
It would be fine if I were just a passerby, but I seem to have the same mother as the male protagonist.
The domineering father, the noble mother, the actor who is the best actor is my brother, and the popular little girl is my future sister-in-law. I am afraid this character is not meant to go against the grain - but in the original work, the male protagonist is an only son.
Purpose: Work well, live well
