The owner of the tavern, Su Mu, drove and injured the second son, the cat of homeless singer Wei Yichen. In order to compensate, Su Mu let Wei Yichen and the second son live in the tavern and perform to make money. Soon, the tavern was going to be renovated, and Su Mu took the opportunity to ask Wei Yichen to live in his apartment. The two had more opportunities to get along. Over time, the two secretly fell in love and got out of hand. Later, Su Mu fell ill, and Wei Yichen took good care of her and stayed by his side. The two lived a magical life. Soon, Su Mu recovered from his illness and the tavern was renovated. Wei Yichen, who was used to wandering, decided to leave, so he secretly took the second young master away and continued wandering. After Wei Yichen left, the name of the tavern changed: He Rijun will come again. One night, when Su Mu was closing the door, he heard a cat meowing, and a man carrying a guitar stood under a streetlight not far away.
