What should I do if I attack the protagonist through the book?

It took Gu Yu 20 years to realize that he turned out to be the vicious cannon fodder male supporting role in a novel.Forcing the protagonist to sign a contract, and being playful and affectionate, he ended up with his family ruined and his family destroyed.Just when he was about to establish a good relationship with the protagonist Gong and take advantage of the loopholes in the plot, who would have imagined that the protagonist Gong in the book, the cruel boss who never got along with the protagonist in the end, was actually abandoned by him in high school? Ex-boyfriend? !Oh ho!Gu Yu: Thank you for the invitation, please do not disturb.Gu Yu, who was forced to go through the plot, faced the furious protagonist Gong who seemed about to commit murder in the next second, his ex-boyfriend, who was holding the wife of the future protagonist Gong in his arms, and his current gossip, numbly chanting Line: "I warn you, this is my man." Looking at Fu Yeyu, whose eyes were blazing, and who could pounce on him and tear him apart in the next second, I couldn't help but reflect on myself: Why can't I think about the protagonist's attack? !The main attack is to be a careless gong x irritable boss shou Gu Yu x Fu Huayu
