After leaving Seoul with an unfortunate wound to her pride, **Yoon Bom** is assigned to a high school in **Shinsoo-eup** as an exchange teacher. Planning to endure just one more year before returning to Seoul, she spends each day detached, with no intention of forming bonds with anyone. Then, one midwinter day, a man barges into her life—**Seon Jaegyu**, wearing a short-sleeved functional shirt in the freezing cold, tattoo sleeves, and speaking in an odd dialect. **“Beautiful.”** He blurts it out to her face without warning. Who *is* this man? After that baffling first encounter, Bom meets Jaegyu again—this time as the guardian and uncle of her newly assigned student, **Seon Hangyeol**. **“If it’s just a four-year age gap, no need to check the compatibility.”** With that outrageous line, Seon Jaegyu begins his bold, no-holds-barred pursuit of Yoon Bom.
