Premise
The story follows Lu Junxi and Han Tuo, who have grown up together since childhood and settle nearly every disagreement with rock-paper-scissors, a game Han Tuo almost always wins. Junxi is energetic and stubborn, while Tuo is effortlessly good at whatever he tries. At university, Tuo challenges his friend under the guise of "relationship training," staging simulated dates and kissing practice, and a boundary is crossed. From fake dating to fake kissing, Junxi gradually is moved by Tuo's sincere feelings, and the two begin a secret relationship.1 • 4
The romance then faces outside pressure. The couple hides their relationship while dealing with family opposition, the pursuit of Junxi's internship supervisor Vincent (Zhan Wensen), and the demand from Tuo's father that he give up his dream of architecture and take over the family business. As graduation approaches, Junxi is also burdened by his father's illness, and the two must choose between making the relationship public or separating.6
A recurring motif is the pair's childhood habit of deciding things by rock-paper-scissors, which the Japanese release notes describe as the frame for a youth love story about feelings changing from friendship to romantic love.3
