After Rebirth, Mrs. He Dotes On Her Husband - Chapter 485 - : The Picture Can’t Be Fake

Han Dong works as an extra as well as a fortuneteller who foretells marriage fortunes extremely accurately. One day, he accidentally foretells his own fortune and discovers that he and a Mr. Golden will become “a match predestined by fate”. As a straight man, he doesn’t hesitate to ruin his image in front of Mr. Golden — acting as a fool, a despicable man, making himself as annoying as possible because he is afraid that the other man will take a liking to him.

A skilled but unfortunate modern-day assassin was killed in a freak accident. However, he soon found himself summoned to another world by an evil wizard, who had him possess the body of a boy as an experiment. After successfully planning the evil wizard’s downfall, he used the wizard’s body as a springboard to gain influence and power in his new world.
