In the early stage, the campus sweetheart has a two-way secret love; in the middle stage, there is family opposition, misunderstandings, and heart-wrenching separation; in the later stage, they reunite after a long separation, and the male protagonist chases his wife in the crematorium, and reunites after breaking the mirror. The ending of the ultimate sweet pet echoes the sense of fate of "the pear blossom reflects the begonia, and you will stay with one person for the rest of your life."
