It takes "reunion after a long absence on campus + gentle pursuit of wife + two-way growth" as the core. An unexpected encounter after a long separation awakens dusty memories. The female protagonist has grown from a timid and sensitive school girl on campus to an independent and sober professional; the male protagonist has transformed from a high-spirited senior to a calm and restrained senior in the industry. After the reunion, the two healed each other and made up for the regrets of the past over time, combining the delicacy of youthful memories with the pull of adult emotions.
