"Cai Xukun, why do you want to be a trainee?" "Because the stage has always been the most free place for me... What about you?" "Me, I don't know. I used to think that I was good-looking and could sing and dance, so it would be a pity not to be a trainee." "What about now?" "Now..." At the end of 2015, Cheng Ai, who was a trainee, met Cai Xukun, who was about to become a trainee. Falling in love at first sight seemed to be a very simple thing. She told him to accept farewell calmly, because it was for the sake of meeting each other better. So after she left, he told his fans that those who have never met will meet sooner or later. When they reunited two years later, he was no longer the Cai Xukun who had a bad temper with her and was occasionally arrogant. Even when no one was around, he looked calm and calm, and there seemed to be no wave in his eyes. He became calm, reserved, more... Cautious. "Cheng Ai, please wait for me." He lowered his head and whispered in her ear, "Wait for me, and soon, I will be standing by your side." His eyes revealed the tenderness, focus and warmth that only belonged to her.
