Fake Pure Love, Real Restriction-Novel Protagonist

As a member of the wholesome romance department, System 016 carefully selected a gentle, beautiful Host who kept to themself and whose relationship with their boyfriend was harmonious and loving. They were a match made in heaven! The moment the stealth binding was complete, the System covered its eyes and shrieked. How could its Host be the protagonist of an explicit novel?! Arc 1: Shen Yu chose his current boyfriend to escape the monsters. Who knew the System would suddenly appear and say it had to save him? Because his boyfriend, who had a cuckolding fetish, would find people to do unspeakable things to him, then abandon him, leaving him to fall into ruin and meet a tragic end. Shen Yu thought the System was an idiot. If it wanted to scare him, it would be better off saying a monster was lurking in the dark, watching him. It was only when he really started heading step by step toward the ending the System had predicted that he realized the monster was already by his side. Wearing human skin. Shen Yu couldn't tell which person around him was It, so he kept one steady while seducing the other, trying to make them kill each other. Sitting beside the corpses, he thought he could finally be free. Suddenly, footsteps approached, and someone put an arm around him. The words by his ear were cold, strangely intimate. "Honey, you killed the wrong me again." Shen Yu's breath caught. Arc 2: *Money-grubbing, teasing, cold on the outside and colder on the inside gong x sharp-tongued, insanely rich shou who could bore through the Earth Lu Cheng couldn't stand Luo Yunan. Especially after discovering that Luo Yunan put on an aloof and virtuous front, yet secretly got into rich men's cars. He despised him even more. Who knew that one day the System would appear? Lu Cheng was told that Luo Yunan was the protagonist of an explicit novel, used as a *** every day. But what did that have to do with him? They were mortal enemies! The System even wanted him to help Luo Yunan. Lu Cheng sneered. "If Luo Yunan is willing to work like a horse for me, I might consider saving him." The System kept pestering him, until Lu Cheng couldn't take it anymore. He pretended to agree, then went over to mock Luo Yunan, only to get a stinging retort in return. Furious, he couldn't understand why, when those mesmerizing phoenix eyes slanted toward him, all he could think about was Luo Yunan, filthy and utterly debased. The next time he saw Luo Yunan being taken away by someone, Lu Cheng followed without thinking. As he gripped the steering wheel, he suddenly realized that compared to the man in that car, he was much younger and richer. So, if he wanted to save Luo Yunan more effectively, wasn't it perfectly reasonable to tell a few lies? Theme: Cherish your feelings.
