Siheyuan: I Married Huairu, and Everyone Calls Me a Fool

[Courtyard drama + taking on the scoundrels + sly protagonist + if you dislike Huairu, stay away] Chen Changguo transmigrates into Love in the Courtyard and awakens an Anti-Bloodsucking System. Whenever someone takes advantage of him, he gets billions of times the value back. Chen Changguo keeps an eye on Qin Huairu, the young woman who wanders around his home all day. If he marries into the Qin family, won't he get generous System rewards every single day? No sooner said than done. Chen Changguo forces Qin Huairu to marry him. Her sharp-tongued mother-in-law, Jia Zhangshi? He doesn't want her. Out she goes! The so-called “Thief Saint,” Banggeng? He doesn't want him either. He'll find a chance to send him to prison! Everyone secretly laughs at him for taking on another man's leftovers, calling him a bona fide sucker. By then, Chen Changguo is already living happily, with plenty to eat and wear and someone there to serve him.
