At Seoul Imperial University, Lalisa Manoban, Kim Jisoo and Kang Seulgi are known as the Crown Trio, three gorgeous, wealthy, intersex ,whose popularity makes them practically royalty on campus. Then three beautiful transfer students arrive. Irene, Rosé and Jennie are triplet sisters, born only minutes apart. Irene is the eldest, Rosé the middle sister, while Jennie youngest by eleven minutes, is shamelessly treated as the baby of the family. Before long, Lisa falls hopelessly for Jennie, Jisoo is captivated by Rosé, and Seulgi finds herself drawn to Irene. But dating the Crown Trio comes with a price. Jealous students begin targeting the sisters, believing they are ordinary girls who can easily be intimidated. Whenever trouble comes, Lisa, Jisoo and Seulgi rush to protect them never questioning why the bullies somehow always look more frightened than their supposedly helpless girlfriends. Because the three innocent-looking sisters are hiding one enormous secret. Their parents aren't merely wealthy. They lead the most powerful and feared Mafia empire in Asia, commanding enough influence to make CEOs, politicians, world leaders and criminal organisations think twice before crossing them. And their three precious daughters? They've been trained since childhood. The Crown Trio thinks they're protecting three innocent princesses. They have absolutely no idea they're falling in love with Asia's three most untouchable Mafia princesses.

Peace was never built to last in Lisa Manoban's world. With Kaito gone, the underworld turns into a feeding frenzy. Rival clans see her empire as ripe for the taking-and the hospital, her most guarded asset, becomes their battlefield. Two of the most ruthless organizations unite against her, leveraging blood, fear, and corruption to claim everything she's built. Jennie Kim, now Assistant Director of the hospital, finds herself in the crosshairs again. But this time, Lisa refuses to shield her from the truth. No more secrets, no more half-truths-Jennie is brought fully into Lisa's war. The revelation comes just in time, because when the enemy strikes mid-surgery, Lisa and Jennie are forced to fight side-by-side, their love and survival depending on each other's hands. Meanwhile, Rosé faces her own war within the hospital board. They demand Lisa's influence be cut off entirely, threatening Rosé's position if she refuses. Caught between loyalty and survival, Rosé must choose whether to stand with her sister or surrender to the politics closing in. Blood will be spilled, alliances will shatter, and in the end, Lisa will have to decide how much of her humanity she can keep-before the crossfire consumes them all.

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.
