The ultimate hierarchy society—K-company. Among them, Se-yeon is a contract employee positioned at the very bottom of the company’s food chain. Today again, tasks assigned from above slide down like a playground slide and land squarely on her desk.

What will become of the push-and-pull relationship between the two?
