Su Nian, a graduate student in architecture, accidentally overhears an intern talking in the break room. The intern says that Lin Yu, her ex-boyfriend of two years, has heard that she's been mentioning him a lot lately. The news awakens memories she had long buried: the regretful breakup in the pouring rain on graduation day, when they'd chosen different paths for their futures, and the lingering feelings woven into the small moments of everyday life over the past two years.
Summoning her courage, she messages Lin Yu, first asking about his recent projects, then honestly asking whether the rumor is true. Lin Yu's reply dispels all her doubts. He not only confirms that he'd heard about it, but bluntly admits that he's been waiting for her to make the first move. At last, using a project as an excuse, Su Nian invites him to meet. In the frank words “I heard you missed me” and the response that follows, feelings delayed for two years find their way back to each other, and their unfinished story begins anew.
