In this day and age, same-sex marriage has become the norm. After failing at both marriage hunting and relationships, I have recklessly fallen in love with my coworker, Odajima, a super high-spec, perfect, handsome man.

In an age when same-sex marriage is the norm...
Gloomy office worker Ichigi has totally given up on marriage. After all, marriage isn't the key to happiness! Ichigi is perfectly happy to be on his own! Besides, it's not like his long-unrequited crush on his colleague, Odajima, is going anywhere...
That is, until Ichigi braves a blind date only to find himself face-to-face with Mr. Perfect! Weirder still, Odajima seems enthusiastic about partnering up with Ichigi, and makes a shocking proposition: "Why don't we try living together for just one year?"
How is Ichigi supposed to keep his feelings for Odajima hidden for a whole year?! Plus, there's no way Odajima could be serious about marrying someone like him... is there?
