South Korea's "musical wonder girl" Marisa came to China.
Returning to the campus where she had been away for a long time,
What she came to look for were the fragments of her lost memory.
The ice-like childhood playmate Gu Nifeng always reminds her of something.
The student council president Mu Zhenyan, who has a bright and gloomy childhood, has always been by her side.
The piano prince Wan Qili, who is as gentle as water, protects her in his own way
The three people have very different personalities but have the same feelings for her.
Slow step, dancing a waltz step by step,
The man waiting for her in the middle of the dance floor
Who is it?
