She was never supposed to be his hero. A doctor who lives in hospital hallways and sleepless nights, Y/N has spent her life saving others while quietly breaking herself apart. At a single fan meeting, one violent moment changes everything-placing her in front of a blade meant for Kim Seungmin, and binding their lives together in blood, silence, and unfinished words. What follows isn't a fairytale romance. It's soft glances across clinic beds. Late-night check-in texts. Hands that linger a second too long. A love that grows in the quiet spaces between chaos and care. He's an idol adored by millions. She's the woman who never lets anyone take care of her. But when the world keeps demanding her strength, he becomes the one who notices the bruises she hides-and refuses to look away. Because some loves don't start with confessions. They start with staying. And this one... might be the most dangerous kind of all.
