Zhou Heng is a mute who has been unable to speak since he was a child, but he has good grades and is very motivated. He has been bullied by his classmates in junior high school and meets a "girl" Pei Huan who saves him.
Pei Huan has been keen on growing his hair long since elementary school. He was always regarded as a girl until he went to junior high school and helped a little boy who was bullied. The little boy wrote on his hand "Thank you sister." "... I am not a girl."
