Yoon Bom, who carries painful scars from Seoul, comes to Shinsu-eup as an exchange teacher at a high school.
She plans to endure just one more year before going back to Seoul, so she spends each day without getting attached to anyone. But then, out of nowhere, a man wearing a functional short-sleeve shirt in the middle of winter, sporting tattoo sleeves, and speaking in a strange dialect suddenly appears in her life – Seon Jaegyu.
“Beautiful.”
Who is this man, saying things like that right to my face?
After their absurd first meeting, Bom meets Jaegyu again, this time as the uncle and guardian of Seon Han-gyeol, a student in her class.
“With just a four-year age difference, we don’t even need to check our compatibility.”
With this outrageous comment, Seon Jaegyu’s unstoppable straightforward flirting towards Bom begins.
