On the first day of college, Gu Cheng is publicly dumped by his girlfriend of three years for being poor. But fate unexpectedly brings him back together with Xia Yuan, the aloof campus belle of Jing University. What nobody knows is that this seemingly unattainable goddess was once the girl he rejected years ago. After deciding to share a rental, the two end up living under the same roof. Although she acts cold and distant in public, she secretly favors him in private. She even hides behind her identity as a novelist, using her search for inspiration as an excuse to ask him about his interactions with his female housemate. Gu Cheng believes their past is long behind them, but through one heart-fluttering encounter after another, he discovers that her seemingly accidental approaches are actually the result of a crush she has kept hidden for years. From missed chances in their youth to sharing every day together.
