There is probably no one in this world who knows better than Lin Xiaozhuang and Lin Xiaoyan what it means to depend on each other for life, because they are twins with the same blood, knowing each other, sharing worries and joys, until one day they fell in love with the same boy.

The sister won't let go, the same-sex barrier, the secular world are all obstacles, the interference of each other's family, and the colored eyes of friends. Faced with these, what should we do?
