Stealing Fortune: Starting by Taking Care of My Boss's Fiancée

They say everyone is born equal, but Jiang Yang knows that's complete bullshit! People are born into different stations in life, and for an ordinary delivery driver like him, getting ahead is harder than reaching the sky. But after gaining the Fortune Plundering System, Jiang Yang finally gets it: if he can steal the protagonists' opportunities, he can become the world's one and only Child of Fortune? Enough talk. Time to get to work! His boss looks down on him and says he's a nobody, so he eagerly helps his sister-in-law with all sorts of problems. A rich heir wants him dead, but before long, he becomes the boyfriend of the heir's dream girl. The jerk downstairs bullies his parents, but Jiang Yang puts the past behind him and drops by to fix the neighbor's fiancée's air conditioner. Once Jiang Yang becomes the one and only Child of Fortune, he looks at the 99+ messages from all the female leads on his phone and sighs. "I can't keep up. There's just too much to do."
