The girlfriend cheats with the superior, yet the rightful boyfriend is scolded as the "home-wrecker"! Lu Yuan, the love song prince who has been shelved for ten years, with his contract expiring, is still forced to admit fault and permanently quit the music industry. On the first day of concert ticket sales, only seven tickets were sold, and right before going on stage, all old songs were banned by the company. The ex-girlfriend sets conditions to admit to being the "home-wrecker" so that he is allowed to sing two old songs. Lu Yuan pushes back the statement and turns around to mount the stage: "The first song, the new song 《Dusk》." The song reduces the whole audience to tears, the song queen ex-girlfriend can no longer sit still, and the superior who shelved him pursues him overnight to ask how many songs he actually still has in his hands.
