She is Chen Lan, a genius girl with a lonely personality, and Chen Mo's sister.
She is Chen Mo, the pearl of the Chen family, a bright and indulgent little princess, and the younger sister raised by Chen Lan.
There is a piece of household registration book between them that is not related by blood, and there is also an abyss of secular ethics between them.
Chen Lan spent half his life as a prisoner, burying his transgressive desire for his sister deep in his heart, and was willing to live like an isolated island. As for Chen Mo, from dependence in childhood to possession in adolescence, that emotion has quietly deteriorated over the years, and finally broke through the dam of taboos.
Four years ago, Chen Mo confessed his love on the rainy night of his eighteenth birthday, but was pushed away by the panicked Chen Lan and fled to a foreign country.
Four years later, Chen Mo returned due to a sudden engagement invitation, only to find that the person who said she wanted to get married was the sister she longed for.
When the inevitable two meet again, will they reunite, or will they be doomed?
Under the oppression of patriarchy and the scrutiny of the secular world, how will these two sisters who depend on each other cross the pond and find their own salvation in a family where repression and tenderness coexist?
Intention: Love can overcome all difficulties and cross thousands of mountains
