The protagonist Lin Zhou (can be customized) is an ordinary office worker/student. He falls in love at first sight with Su Wan (can be customized) who comes from a wealthy family and has a gentle personality, and begins a clumsy but passionate pursuit. He frugally gave her gifts, took detours to accompany her to and from get off work, and helped her immediately when she encountered difficulties. He regarded Su Wan as the light of his life. Lin Zhou carefully prepared his confession, but unexpectedly ran into Su Wan having an intimate interaction with his rich second-generation boyfriend Jiang Chen (customizable). Su Wan politely but clearly rejected Lin Zhou, admitting frankly that the two had "different classes." Lin Zhou felt his self-esteem being crushed for the first time. Lin Zhou showed strong execution and observation skills in his pursuit. He once stayed up late to study a plan to help Su Wan solve work problems. This ability paved the way for subsequent darkening; Jiang Chen showed contempt for Lin Zhou, sowing the seeds of conflict.
