- Description from novelbuddy

Liola—the best assassin in his world—has vowed to kill no more. He was being chased by an assassination organization when he accidentally dropped into a parallel universe: through a dimensional gate and into poor teenager Kaiser’s apartment. Instead of going to the government shelter for lost dimensional travelers, Liola and Kaiser wind up going to school together.

Liola has been trying his best to live the life of an ordinary person, but after certain things happen one after the other, he begins to realize that being an ordinary person could be harder than being an assassin.

There is always such a person in the world, his family background is better than yours, his status is higher than yours, while you work hard and think all the way up, but with just a wave of his hand, you are wiped out. What is even more sad is that he doesn’t even know who you are.

Zheng Jue met Han Jin like this but he didn’t realize this truth until he died. In the end, he had found the wrong opponent and ultimately lost his life.
