Lisa Manoban stood at the center of Jennie Kim's world-and Jennie, unknowingly, still held that place in Lisa's heart. They loved hard, young and wild, in a world that demanded masks and silence. Somewhere between crowded schedules and whispered arguments, their relationship slipped through the cracks. Jennie moved on, or so it seemed. But Lisa never really let go. Now, from the shadows of sold-out concerts and behind anonymous usernames, Lisa watches Jennie shine brighter than ever. She's no longer the girl at her side, but she's still the loudest cheer in the crowd-unseen, unheard, yet unfailingly present. To Jennie, Lisa is a closed chapter. To Lisa, Jennie is still the story. And Jennie has no idea her biggest fan... is her ex.

Jennie Kim is a brilliant doctor - calm, composed, and completely uninterested in distractions. Her clinic runs like clockwork, her white coat is always crisp, and her heart? Completely off-limits. Then comes Lisa Manoban: chaotic, charming, and suspiciously accident-prone. One week it's a sore throat. The next, a bruised elbow from "tripping over nothing." Jennie is convinced Lisa's faking it. Lisa insists she's just following doctor's orders. But when Jennie finally confronts her about the weekly visits, Lisa just grins and says: "Well... you did tell me to come back if the symptoms got worse." Turns out, she wasn't talking about a cold - she was talking about a crush. Now Jennie has a problem. Because the patient she tried so hard to ignore might be the one person who makes her heartbeat skip for real. A slow-burn, feel-good rom-com filled with fake injuries, real feelings, and one very persistent patient who might just cure the doctor's cold heart.
