Reborn as Cannon Fodder, I Win Over the Big Shots by Training Dogs

[Transmigration + male rivals competing for her + female lead has no romantic or sexual history and all male leads are virgins + love rivalry + dog training + no redemption arcs] Su Wu transmigrates into the role of a vicious female supporting character. Her mission is to win over the top-tier male leads, all of whom the original character looked down on. The System promises: Do whatever you like, deliver a convincing performance of deep devotion, and you’ll rake in a massive bonus! Su Wu gives a seductive smile and plays the heartless flirt to perfection. Just as victory is within reach, the System suddenly crashes. “Warning! The reward mechanism has failed! Host must stop pretending and sincerely win them over to survive!” Su Wu: ?! I messed up. Now I really have to throw myself into this devoted performance! Fu Yanci: “Good. You’ve finally admitted you belong to me. (Looking at the others) You can leave now.” Shen Que: “So we’re all part of your collection? Interesting... Then I’ll be the most special one.” Gu Yanzhi: “As long as it’s you, I don’t mind!” Jiang Yubai steps forward and picks Su Wu up: “MVP, back where you belong.” Xie Lin: “Sis~ I knew you couldn’t bear to leave me! Don’t worry, I’ll get along ‘nicely’ with my brothers!” Promises? I stopped believing in them in my twenties! Adults don’t have to choose!
