The Male Lead's Gone Mad, and the Second Male Lead's Broken [Book Transmigration]

Please add my book to your reading list in the sidebar on the right → Qiao Yueya transmigrated into a book: a healing novel about the immortal and demonic realms that she'd read before she died. In the story, the heroine had been the spoiled little junior sister of Qingyue Sword Venerable of the Canglan Sect in her previous life. She was willful and unreasonable, abusing her status to do whatever she wanted. Everyone hated her. Naturally, after Qingyue Sword Venerable broke the rules and took a transmigrated supporting character as his disciple, she turned evil, wreaked havoc, and eventually got herself killed! Then the little junior sister was reborn, and the story began. In this life, relying on her knowledge of the plot, the little junior sister healed, one by one, the people who had been tricked out of their money and feelings by a two-timing heartbreaker: The Demon Lord hero, who had fallen into darkness; The Buddhist disciple second male lead, who had become heartless; The Barbarian King third male lead, who was cruel and violent; The evil spirit fourth male lead, who was obsessed with changing skins. She successfully transformed herself from someone everyone hated into someone everyone loved, in a sweet, healing romance. But Qiao Yueya didn't transmigrate into the heroine, the supporting female character, or any of the male leads or supporting characters. She transmigrated into the two-timing heartbreaker who was fated to die before the first chapter ended: the catalyst who drove the hero and the second, third, and fourth male leads to darkness! Dead from the start. Qiao Yueya: ... Whoever wants to be this catalyst can be it. I'm not doing it. But when she brought up breaking up: Demon Lord hero: Why do you want to break up with me? What's wrong with me compared to them? Buddhist disciple second male lead: I respect your choice, but please don't make me leave you. Barbarian King third male lead: What don't you like about me? I can change! Evil spirit fourth male lead: Are they more beautiful than me? If they're not, why choose them? Qiao Yueya: ... Are you guys crazy or something? Theme: Focus on your career, not romance.
