Fate conspires when Tang Su realizes her longtime crush, the distant Doctor Lu, occupies the apartment across the hall—eight years have passed, yet he remains oblivious to her existence. Forced to suppress her feelings, she maintains a facade of professional courtesy, greeting him only as "Doctor Lu" whenever their paths cross. Everything changes the afternoon Tang Su enters his office while he sleeps. The duty nurse chases after her, alarmed, only to find Tang Su lounging in his chair with her leg stretched toward him, playfully requesting, "Doctor Lu, could you examine my leg? It's been bothering me." Lu Han orders the bewildered nurse out, shutting the door behind her. Moments later, the nurse witnesses Tang Su limping back through the corridor, tears streaming down her face. The nurse smirks, assuming another woman has fallen victim to Doctor Lu's cold rejection. Then Lu Han emerges from his office and, catching sight of Tang Su, sweeps her into his arms without hesitation. He carries her back inside, whispering urgently, "Didn't I tell you to stay put? Why are you walking on that injured leg?" Marriage follows, but Doctor Lu's schedule becomes suffocating—surgeries, conferences, and medical seminars keep him perpetually absent, leaving Tang Su feeling abandoned. Her TikTok bio shifts to: "Living like a widow." Until a stormy evening arrives. Doctor Lu returns home, and everything shifts. Tang Su quickly updates her bio: "Please spare me."
