I Had No Choice but to Marry the Dragon-Proud Male Lead [Quick Transmigration]

He's cannon fodder. His only purpose is to help build the protagonists' romances, while staying out of the limelight. 1. [The Beautiful, Vicious Sister-in-Law] He's the future sister-in-law of the Dragon-Aotian protagonist. He smiles sweetly at his younger brother-in-law when his fiance is around. As soon as his fiance is gone, he turns on him, treats him like a servant, and flirts with other people on the side... Later, his brother-in-law, now a Dragon-Aotian, corners him step by step. "Sister-in-law, you wouldn't want Big Brother to find out about the bad things you've done, would you..." 2. [The Only Ordinary Person in the Dragon-Aotian Dorm] Three people in the dorm are Dragon-Aotians. He's the only ordinary one. Sensitive and insecure, he constantly thinks they look down on him, so he dresses as a woman and dates them online, hoping to trick them into sending him pictures that he can use to smear their private lives on the forum... In the end, the truth comes out. The Dragon-Aotians shut the dorm door, and the room is filled with all kinds of little skirts. "You like wearing them, don't you? We'll make sure you get your fill." 3. [The Husband Who Falls Asleep on Cue] His OMEGA boyfriend is adored by everyone. According to the plot, his boss and his friend will sneak off to meet his boyfriend while he's asleep... All he has to do is lie down and fall asleep. As he lies on the sofa pretending to be asleep, his usually gentle OMEGA boyfriend curses his friend for being a homewrecker, and a warm kiss lands on his cheek. The Dragon-Aotian boss speaks in a restrained, controlled voice: "If you don't break up with him, I'm really going to lose it." 4. [The Fiancee in a Broken Engagement Story] He's engaged to the Dragon-Aotian, but he's also involved with one of the Dragon-Aotian's classmates. He orders the Dragon-Aotian around and mocks him in public, then breaks off the engagement, making him a laughingstock... Later, the Dragon-Aotian has achieved great success and offers him a rare treasure. "If you don't want to marry me, how about I marry into your family?" Theme: 1
