Seo Hyunsoo is sure of one thing: people are scum and they will always disappoint you. Sure enough, at his very first company dinner after his transfer to a new department, he finds his coworker, the obnoxiously upbeat Baek Youngchan, performing an unsavory deed in the men’s bathroom.

Or will these two clashing coworkers find that opposites really do attract?
