Some humans known as omegas go into heat every month and are overwhelmed with lust. During this time, the only things that can sate their urges are powerful prescription medications or the company of certain humans known as alphas. Despite his reputation as a reliable employee, Akitsugu Suzuya has a secret: his heat suppressants are much more effective than he claims, and the time he takes off from work every month is just to drink beer and play video games. When concerned new hire and alpha Shouta Furuike shows up at his apartment to offer companionship during Suzuya's heat, Suzuya is willing to do anything to make sure his lie is not exposed. But when Furuike bites Suzuya's neck during the throes of passion and thinks he bonded them to each other, Suzuya realizes that his lie is spiraling far out of his control. [Written by MAL Rewrite]
