The First F-Rank Hunter to Fix Her Rank

Yerin was still paying F-rank insurance premiums when a strange old certificate turned up between donated books in her shop. The name on it belonged to a winner from thirty years ago, but no one in Seoul had a single record of that person. Then Junseo, a sharp-tongued repeat customer, started treating her like a problem he meant to solve and a woman he meant to corner. He humiliated her, pushed her rank error into the open, and kept coming back with new reasons to stare at the same faded paper. Yerin hated how fast he got under her skin, especially when his hands were gentler than his words. He was the last person she should trust, and the first person who noticed when her composure cracked.
