Transmigrated Into An Adult Game

A young man dies after playing an R-18 game all night and finds himself standing infront of an headless shadow.

"Welcome to the world of the Devil hidden in the shadow, dear player." The headless shadow announced.

"Holdup, isn't that title of r-18 game i played a while back." The young man couldn't help but get startled.

"I don't want to go."

"We've some explicit videos of yours."

"Fine, I'm willing."

The journey of a main character who'll overwhelm this new world by any critical compromises.

Note: My English is not that good so be ready for it when it hits you in the back.
