When he was eighteen years old, a text message ended the first love between Yang Chuyi and Lin Yule, and Yang Chuyi went to South Korea to become a trainee. Seven years later, he returned to China as a top idol "Seven", but he was caught in a whirlpool of public opinion due to a dispute over contract termination.
Lin Yule thought that the relationship had long since ended. She is the editor of a magazine, has a stable life, and has her senior student Zhou Yuhang who silently protects her. It wasn't until they reunited at a small wedding that she discovered that some people never really leave.
From the "coincidental" move-in of the neighbor across the door, to the unexpected sincerity during the interview, to the drunken confession, the truth about the text messages back then, and the subsequent "proposal" at the concert, the barriers built up over the past seven years are crumbling little by little. But what stands between them is not just the misunderstanding of the year - there are also lawsuits, public opinion pressure, and the cruel reality that an idol cannot fall in love. When the misunderstanding is solved, they rush to each other desperately, and finally discover that love has never left...
When an old love reunites, is it a repeat of the past, or is it a reunion of sorts? The answer is hidden in the forest blowing through this autumn.
