On his first day of junior high, Kei Enjoji fell in love at first sight.

Now adults and living happily together as a couple, things seem to be going well for Ranmaru and Kei. One morning, host Kei arrives home after a night out drinking with a client. A frequent occurrence, Ranmaru is initially unfazed by Kei's drunken state—until he notices three extremely suspicious things: Kei's clothing smells of makeup, his chest is stained with lipstick, and he is carrying matches branded with the name of a love hotel. To top it all off, a woman calls the apartment asking for "Kei-chan," and at that, Ranmaru loses it. Hurt by Kei's unfaithful actions, Ranmaru storms off.

If this is what society wants, and if Kei has truly fallen for a woman, then who is he to stand in their way?
