Dr. Kwon Saebi, is a brilliant internal medicine resident known for her cold demeanor and focus. Calm and composed, Saebi doesn't get emotionally attached to patients-she can't afford to. Not after what happened during her first year in residency. She keeps a strict wall between her heart and her profession.
But her world begins to shift the day Myung Jaehyun, is admitted under her care.
Jaehyun is a long-term patient with a chronic heart condition that worsened suddenly. Despite the pain, and the occasional brushes with danger, he never loses his signature soft smile. He jokes with the nurses, comforts other patients, and acts as though he's just on a vacation. His cheerfulness irritates Saebi at first. She thinks it's a mask-a form of denial. But the longer she treats him, the more she begins to see that Jaehyun isn't smiling to hide his pain. He's smiling because he's accepted it. And because he doesn't want anyone else to worry.
Over shared late-night checkups, walks through hospital corridors, and stolen conversations when the ward is quiet, Saebi begins to open up to him. Slowly, Jaehyun climbed at her guarded heart. He listens, asks questions she hasn't heard in years, and notices the loneliness in her eyes when no one else does.
But time isn't on their side. Jaehyun's condition is progressive. Surgery is risky. Every day, Saebi fears that the next chart she reads will be the one that breaks her.
Jaehyun, meanwhile, finds himself falling for the doctor who finally sees him as more than just a patient. He wants to live-not just survive-for her. But he also doesn't want her burdened with the weight of loving someone who might actually...
not make it.
