Mr. CEO, Please Stay - Chapter 938

I, Kang Woojin, was quitting my design work and became a jobless person. The next day, my friend took me to auditions and I was forced to perform.

As i was given a script, the void space appeared in my mind and forced me to relive the character.

I got stabbed. Became a serial killer. Became an Exorcist.

As I become an actor, the misunderstandings keeps growing day by day.

A 30-year-old NEET is reincarnated into the body of an otaku that choked to death on instant noodles. As he comes to grips with his new life, he realizes that this world is subtly different from Earth. The denizens of this world are far better looking, and this new world also possesses futuristic technology as well as mysterious Yin Yang masters!

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?
