A Sequal to "Fake Fact Lips"

Since high school, Ryo and Zen have been rivals in all sorts of things. Now competing with each other in the sales department.
The two started drinking and had a rather arrogant game of "whoever cums first, loses" and they ended up becoming lovers. However, the two of them still can't be honest with each other and continue their "game" of competition.
Although they're now lovers, they are too busy with work and struggle to find time to spend together and begin to drift apart.

"I get jealous over small things."

While battling these emotions, Ryo and Zen face a new challenge when an old colleague, Futami, transfers to their office from the Osaka branch and proclaims "I want to join in your competition"?!?!?

Can the two keep their relationship private and learn to communicate their feelings truthfully? Will they deepen their love or falter to uncool heads, jealousy, and spite?
