By chance, Seon Chaek meets Bun and ends up spending the night at his place. The next day, Bun wishes to rush to arrange a wedding with Seon Chaek, but Seon Chaek has no intention of marrying him. She begins plotting clever ways to escape the situation. Will Seon Chaek's plans succeed? Meanwhile, she finds herself threatened by thugs in the woods. That's when a mysterious man suddenly appears to help her.

Bun shocks everyone in the Astral Philosophy Club by announcing that he's going to marry Sun Chaek. To make matters worse, Bun goes to Sun Chaek's family and claims that she took his innocence and that is the reason they must get married. However, Sun Chaek's father firmly opposes the idea.
