Su Qingyuan, a 32-year-old associate chief cardiologist, lives alone with her five-year-old daughter Niannian. Her ex-husband’s betrayal has made her build a wall around her heart, and she wants nothing to do with age-gap romances. Then one night, when her daughter develops a high fever and is rushed to the emergency room, Su Qingyuan reunites with Lu Xingyan, a 24-year-old top-tier star in competitive gaming. This rebellious, cocky “jungle maniac” not only helps her with everything she needs, but slowly finds his way into her life under the pretext of repaying a debt of gratitude.
Su Qingyuan doesn’t know that Lu Xingyan is the heart patient she saved from the brink of death five years ago. The medical instructions she wrote back then are still his phone wallpaper. He plays games with Niannian and learns to make baby food. When Su Qingyuan is harassed by a violent patient, he steps in front of her, using his passionate yet thoughtful care to melt away her armor of reason.
But prejudice over their age gap, rumors in the gaming world, her ex-husband’s interference as he fights for custody, and Lu Xingyan’s sudden heart condition relapse repeatedly put their relationship in crisis. Fortunately, Niannian’s “helpful matchmaking” and their understanding of each other’s careers teach them to fight side by side: she uses her medical expertise to protect his health, while his maturity and sense of responsibility ease her anxiety.
When Lu Xingyan declares on the championship podium, “Half of my championship belongs to Dr. Su,” and Su Qingyuan holds his hand and says, “I don’t need a perfect partner. I only need you,” the love that began with a doctor and patient reuniting and culminated in mutual healing finally delivers a perfect “heart-rate diagnosis report.”
