Seventeen-year-old Lin Zhixia is the best girl in her grade. Her only secret is the deeply creased concert ticket in the mezzanine of her schoolbag. On a rainstorm night three years ago, she lost her idol Ji Xingye's concert ticket, but he found it. The phrase "I will sing to you next time" became the light of her entire youth. And Ji Xingye, the rock and roll boy who is sought after by all the girls in the school, never knew that there would always be an extra bottle of throat lozenges backstage at every performance, and he didn't know that the eyes at the end of the corridor were looking at him quietly. When the college entrance examination countdown sign was put up on the blackboard, Lin Zhixia decided to complete three things before graduation: return the ticket to him, say thank you personally, and then formally bid farewell to this silent secret love. But when she finally plucked up the courage, she discovered that Ji Xingye was no longer the boy she remembered - or in other words, she had never really known him.
