A world where love is regulated by the state.

Confessions, dating, and gifts for the purpose of romance. The emotion of seeking a "specific someone" is forbidden as something that clouds judgment and disturbs social order.

One day, Ito Fujishiro, an officer from the National Love Enforcement Bureau, comes to you under suspicion of violating the Love Prohibition Law.

The investigation is over. No charges. Normally, that should have been the end of your relationship.

And yet, he is in your room again today.

There's no need to make any one person special. The man who always thought so somehow won't leave your side.

An officer and a former suspect. Until the feeling of "it has to be this person" finally finds its name.
