“Wanna team up with me?”

Forced into the human hunting ground “Utopia Sodom” to pay off the debt left by his drug-addict father, Lee Yeonwoo is dragged into hell.

However, thanks to his uniquely altruistic survival strategies, Yeonwoo lasts longer than anyone ever has—

catching the attention of Cheon Wooshin, who rescues him from the hunting ground and offers him a place on his investigation team.

While investigating the identity of the biochemical terror drug “Snake Venom” as a team,

the logical and refined Cheon Wooshin suddenly vanishes—

only for a wild beast with filthy words and primal instincts to take his place and pin Yeonwoo down.

“F**-ck, you smell so f**king good.”

Confronted by an unexpected, secret side of Cheon Wooshin, can Yeonwoo keep their investigation on track?
