Lin Shen has a tough temperament because his mother likes gentle girls and is often restrained. He is particularly envious of his brother and wants to be a boy.
But the magical two people swap bodies, allowing her to enjoy freedom.
Because He Yuan's personality is too gentle, it is difficult for him to talk to his father and grandfather about their worries. The two exchanged bodies because of a magical wishing coin that year.
Lin Shen: We all have a secret.
He Yuan: In this unstable world, only you can recognize me.
