The Circumstances of an idiot

Eun-gyo, after breaking up with her trashy ex-boyfriend, runs a café with her friend Kim Hae-da, enjoying a peaceful everyday life.

But this tranquil existence is disrupted by the arrival of a new person.

“Sunbae, I like you. It was love at first sight.”

Lee Jae-heon — young, handsome, and with a slightly twisted side.

Eun-gyo, too, begins to feel drawn to Jae-heon, who boldly approaches her.

However…

As Eun-gyo's life is already shaken by this new relationship, even bigger waves begin to crash upon her.
