I Transmigrated Into the Crown Prince's Fussy Ex, and He Kissed Me to Tears

【1v1 + mutual devotion + sweet romance】 A wealthy heir who seems restrained and well-mannered but is insatiable (183 cm / 21) x a big-eyed, adorable yet spoiled beauty (165 cm) Lin Zhenmeng transmigrates into the body of the wealthy young heir's troublemaking ex-girlfriend. The System requires her to act as his foil: be spoiled, suspicious, and bad-tempered, making his life miserable until he breaks up with her, so he can accept the gentle, virtuous fiancée chosen for him by his family. She kicks him out of bed in the middle of the night and makes him cook noodles, imposes a curfew, sneaks a look at his phone, tears up contracts, and toys with his Adam's apple and abs. After seven rounds in one night, her poor little waist is on the verge of giving out, yet she still tells him he is no good. She keeps recklessly dancing all over his boundaries... But why does he seem to love her more and more? He thinks she loves him desperately and wants him to have eyes for no one but her. If she can't see him, she gets distressed. Her increasingly spoiled and willful behavior earns her his frenzied retaliation. He pins her to the bed and kisses her until her eyes are red. Shen Zhixu: Baby, from now on, every time you act up or throw a tantrum for no reason, this is how I'll punish you. I'll kiss you until you behave. Got it? Trembling from his kisses, she asks, “When are you going to break up with me and get together with your destined match?” Shen Zhixu: “Destined match? Baby, you're my destined match!” System: “Wait, that's not right. Wasn't she supposed to be his ex-girlfriend? How did he end up proposing to her?” Lin Zhenmeng: “I'm vain, greedy, nasty, spoiled, and always making a fuss for no reason.” Shen Zhixu: “Nonsense. My baby is gentle, unpretentious, and understanding.” She acts out, throws tantrums, and plans to run off as soon as she finishes the task. He watches and smiles, completely lovestruck. After she runs away, he catches her and forces her to stay by his side. Later, she discovers that someone has been manipulating the System that keeps pushing her to break up with him! Lin Zhenmeng: “Heroine? Destined match? Your boyfriend is mine now.”
