After Becoming the Villainess, the Male Lead Insists I’m the One He Wants

【Quick transmigration + 1v1 + both leads are each other's first and only + universally adored heroine + hero falls at first sight + rival suitors + no bashing the original heroine】 Su Wanyin is transmigrated into a small world as the villainess. Her mission is to bully the male lead, make the heroine look good, and get the two of them together. Having watched countless short dramas, Su Wanyin is sure she'll be perfect for the job. But as the story unfolds, things start to go wrong. Why is the obsessive male lead always clinging to her, acting like he can't live without her? 【World One: The Crown Prince poses as her fiancé and falls for the spoiled young heiress at first sight】 Su Wanyin looks down on the poor fiancé who comes to see her and makes things difficult for him at every turn. She makes him stand guard outside her room at night and sends him into the river to retrieve things for her. She expects him to hate her, just as he does in the story, but instead he kisses and cuddles her, claiming it's all a reward! When she follows the plot and tries to push him toward the heroine, he pins her to the bed like a madman. “Yinyin, you were the one who came after me first. You can't leave me now.” 【World Two: She wants him for his body, and the young heiress gets tangled up with the Miao lord】 Su Wanyin and her classmates travel to a Miao village to film a documentary, where they rescue a handsome young man who has been bitten by a snake. Wanting him for his body, Su Wanyin uses “threats and persuasion” to make him her boyfriend. She kisses and cuddles him, turning the innocent young man into a lovesick puppy. Later, Su Wanyin remembers the plot and her mission, and makes a quick getaway. But her boyfriend tracks her down, demanding that she take responsibility, and traps her at home to punish her thoroughly. “Yinyin, we already had our wedding in the Miao village. Don't think you can get rid of me.”
