Chen Fan, a second-year law student, has had a crush on his classmate Gu Qingli for a year, but doesn't dare tell her.
Gu Qingli is also a second-year law student.
Hoping to catch her eye, Chen Fan makes an impulsive decision: he joins the martial arts club.
He doesn't know how long he'll be able to keep training, or where this path will lead. He only knows that every Wednesday evening, when she passes the gym, she glances inside through the floor-to-ceiling window.
For that one glance, he gets up at five in the morning to practice his stance. He refuses to quit the club even when the upperclassmen beat him so badly he can't get back up. Through sheer determination, he goes from a complete novice with no experience to making the provincial team, competing nationally, and signing with a professional club.
Meanwhile, she goes from being a law student to an intern lawyer, then a litigator who can handle cases on her own.
Over seven years, the two go from standing on opposite sides of that floor-to-ceiling window, to standing side by side in front of it, and then to having a home and a window of their own.
