Three years after their breakup, Cheng Cheng participated in a love variety show as an amateur, only to find that one of the male guests was her former actor-boyfriend Li Bin. During the show, he was cold and distant, but turned around and announced in public: "I am here to get my first love back." During the game session, Li Bin's cell phone ringtone rang - it was "Happy Breakup" that Chengcheng sang drunkenly three years ago. That night, he cornered her in a corner of the surveillance camera, his eyes red: "This time, you dump me, and then we start over, okay?"
