Rebirth without being a killer

He is the world's top killer, a beautiful metamorphosis, he is always proud and confident, arrogant and unscrupulous, like a giant tiger, a lonely king living in the dark, facing all ignorant humans with cold eyes .The person who knew his true identity has long since disappeared from this world, and no one will find out what kind of person he really is. He integrates into the life of ordinary human beings, with the same stupid and ignorant smile on his face as everyone else. on.He is the king of darkness - Fallen Night.In this way, he fell in love at first sight with a woman called Feng Yu.When the gunshots sounded, he was stunned and couldn't fight back in time because the person who shot him was called Feng Yu.If there is a next life, he hopes to be an ordinary person and fall in love with ordinary people.Fallen Night regained his life and went to live in another world.Is it because God thinks that he is actually entitled to happiness like this? (P: It mainly tells the story of the killer's arrival in another world, but the object of his love has changed from a woman to a man.)
