Little Sister-in-Law, Don't Be Like This. I Really Don't Want to Lie Flat!

Zhang Han's soul travels to 1990 and takes over the body of a fellow named Zhang Han who had the same name and surname and the worst luck imaginable. To marry a wife, the original owner sold off everything he had to scrape together a 5,000-yuan bride price, only for his bride to run off with another man, taking the money with her! To repay and make it up to the original owner, his three younger sisters-in-law take it upon themselves to look after Zhang Han and put him through college. Zhang Han never wanted to be the kind of kept man everyone despises, but then he gets bound to a Kept Man System. He has to live off women to claim rewards... Looks like he won't just have to live off women, he'll have to do it proudly and wholeheartedly, until his three younger sisters-in-law worship him and remain devoted to him!
