a Marriage that Could Ruin us|Shin sokoku

Everyone knows the Armed Detective Agency's Atsushi Nakajima and the Port Mafia's Ryunosuke Akutagawa can't stand each other.

Everyone is wrong.

For over a year, they've hidden a relationship no one could ever suspect, meeting beneath the cover of night while the rest of Yokohama believes they're trying to kill each other. Their secret is safe... until Atsushi begins feeling strangely ill.

What starts as unexplained nausea and exhaustion soon turns into something impossible.

Pregnant.

With enemies on every side, the two are forced into a secret marriage and must hide both their relationship and the growing life they're protecting. As Atsushi's pregnancy becomes harder to conceal, the lies pile up, missions become more dangerous, and the risk of being discovered grows with every passing day.

Only three people know the truth: Ranpo, who figured it out almost immediately; Fukuzawa, the President of the Armed Detective Agency; and Chuuya, the one person Akutagawa trusts with his life.

But secrets never stay buried forever.

When the truth finally comes to light, will the Armed Detective Agency and the Port Mafia accept the impossible... or will the revelation tear everything apart?
