Du Li's life was completely changed by the word "brother-in-law" from a strange girl. He doesn't understand. Is it the dream of a troubled boy to live a happy life and be surrounded by beautiful women? Or was it in his dream that the past had never passed?
But one thing is true, he loved. The "sister" who has lost consciousness in the hospital bed is the girl he has always had a crush on when he was young? Because of the fragrance of a bouquet of flowers, the drop of crystal that soaked out of the corner of "sister"'s eyes, was it for him?
That "brother-in-law" at dusk, was it just a prank? Or a good-natured joke? Or is it a trap hiding a huge secret?
