Hieon is a girl crushed by debt, living in the rotten neighborhood of Changseong. When she is on the verge of being dragged into the red-light district, the one who saves her is Mugil, a gangster who appears like the wind.

“I… I’m good at studying. I can pay off the debt without working in the entertainment district.”

“For someone this small, you’re needlessly admirable. Starting tomorrow, come to work here.”

As Hieon spends time by Mugil’s side, she finds herself sinking deeper and deeper into his kindness. But the moment he realizes her feelings, Mugil suddenly turns cold—completely unlike before…

“Just call me ajusshi. When we’re fucking, I’m not your boss.”
