My brother doesn't call me sister, because he has a wild mind.
Wang Zimu's little Shen Xi is 5 years old. Once she becomes sensible, she no longer calls her sister.
Shen Xi has a secret: her childhood sweetheart's younger brother is the top star Wang Zimu.
Wang Zimu also has a secret: he has always had "her" in his heart.
Wang Zimu returned to China for development and deliberately tried to get close to her secretly, so Shen Ostrich Xi decisively packed up his luggage and ran away.
She ran away from him and he said: "I love you as easy as breathing."
This is the sour and sweet journey of courtship for the younger brother.
Concept: This is a sibling relationship about childhood sweethearts
