99.9%: A Science-Filled Cycle

Man Yong Meidou won a one-day boyfriend in a supermarket raffle, only to discover that the guy was someone he'd rescued in Nagano as a child. He readily accepted the situation and went on a date with him that very night.

During the date, he unexpectedly ran into his freebie boyfriend's childhood friend. Intrigued by the way this stranger he'd never met before looked at him, Man Yong Meidou immediately called in the favor and asked his "boyfriend" to keep pretending they were a couple.

Man Yong Meidou: A police academy student, huh? This is so exciting.

Rei Furuya first saw Man Yong Meidou on a wanted poster. The man was a high-ranking executive in Bonten, guilty of every crime imaginable.

He had always loathed scum like him.

But as he got to know him better, he discovered that being intimate with the man let him return to the past, giving him a chance to rewrite fate. So he set out to win Man Yong Meidou over.

At last, he successfully returned to the timeline when he was attending the police academy, only to face new problems:

1. He seemed to have fallen for that damned Bonten executive.

2. His childhood friend had suddenly gotten a new boyfriend.

3. His childhood friend's new boyfriend was Man Yong Meidou.
