Chen Shu sat in front of the window, watching the stars and the moon sink into darkness, thinking about that boy second after second, year after year.
She thought he would never be able to leave her
Xu Xuan is uninhibited and loves freedom
Chen Shu can't keep him
He wanders around many girls without knowing it
Later someone told him to choose one
He didn't take it seriously
Later, he couldn't leave her
Purpose: redemption
