Dreaming of a peaceful life with his fiancée Heekyung, Lee Yunwoo moves to a quiet rural village where he knows no one. But one day, Heekyung leaves without a word—just a short text ending their engagement.

Abandoned and struggling to adjust to his new teaching post, Yunwoo sinks into isolation… until one unexpected visitor shows up: Heekyung’s younger brother, Chae Jungmin—who also happens to be Yunwoo’s former student from his university tutoring days.

“Hello, teacher. It’s been a while.”
“Or… should I be calling you brother-in-law instead?”

Jungmin ignores Yunwoo’s protests, stepping into the home Yunwoo has refused to clean for fear of erasing Heekyung’s traces. Before long, he makes an unexpected proposal—cohabitation.

“No one to lean on, and here you are still chasing after the woman who left you.”

Unable to firmly turn him away, Yunwoo finds himself sharing his home—and his loneliness—with Jungmin. But can the two really live under the same roof without crossing a line?
