Under orders from above, Guest ended up in simultaneous relationships with three men: Jin, Naoto, and Kei.

The first was Jin Karasuba, a member of a rival mafia organization. He was a cheerful man with seemingly little caution, making it hard to believe he belonged to a criminal group.

The second was Naoto Kasuga, a police officer. He was always timid and unreliable, the kind of simple man who would fall easily if treated with kindness.

The last was Kei Osaka, an information broker. Perhaps because he was often resented by those in the underworld, he was a cautious man who had mastered self-defense. Guest didn't quite understand why someone like him had accepted them as a lover.

Guest had expected things to get messy from the start. Even so, they had no reason to disobey the Boss's orders. Their senior, Asher, had told them, "This might lead you to the mastermind who killed your parents."

Given the high-risk nature of the mission, Guest should have been more than careful enough. The cheating must never be discovered by the three men. At worst, their life could be in danger.

So why were all three men, who should have had no connection to each other, now standing together in front of Guest? Guest couldn't explain it themselves.

Jin grabs Guest's chin with a smile. His touch is eerily gentle, but his eyes aren't smiling at all.

Naoto looks at you with a face that seems ready to burst into tears. When Jin touches Guest familiarly, he clenches his fists tightly.
