How Does a Stupid Cat Mark the Male Protagonist?

Eighteen-year-old Tao Tao transmigrated into a book, an old-school cultivation novel aimed at men, with a broken-engagement storyline. She had become the villainess engaged to the aloof male lead. The System told her to follow the plot and bully the male lead while recklessly courting death. Ying Tao had just presented as an alpha. Armed with her top-alpha certification, she confidently started the job and gave the System an OK sign. The male lead hadn’t reached Foundation Establishment yet and needed food to get by. Tao Tao unceremoniously snatched his meal and coldly tossed him the bitter-melon-flavored nutrition drink with the worst sales in the interstellar market. The male lead fell unconscious in an icy domain. Tao Tao promptly piled on, summoning her Maine Coon spirit beast to stomp him underfoot and dance on him. The male lead dazzled everyone by winning the swordsmanship championship. Tao Tao released her top-alpha white-peach-scented pheromones to suppress him, forcing him to spend the whole day in a cold spring before his mind finally settled. The plot reached its crucial point. The broken engagement, the face-slapping, drugging someone to make them humiliate the righteous male lead, then getting stabbed to death by the male lead, who had endured and bided his time. A glorious curtain call. Ying Tao coldly threw the broken engagement letter at him and mocked him for being delusional. She would never call him baby, bite the back of his neck, and mark a beautiful but useless omega like him. In secret, she lit incense for herself, folded her hands in peaceful prayer, and waited to be written out. A System notification rang out: Mission complete √ Your reward has arrived. You can go home now, kiddo (*σ´∀`)σ! And then... the male lead stabbed her with his sword. No, the male lead’s vines wrapped around her. “Kiddo... Waaaah!” The System’s voice was suddenly cut off, and a piercing alarm rang out. Before her, the usually reserved, taciturn young man set down the matching knot he had just finished making. Unhurriedly, he raised his long, frost-laden lashes, glanced at the broken engagement letter, then hooked a cold finger behind her waist and pulled out the drug she had forgotten to put away. Without a word, he calmly drank it all in front of her. The vines slowly tightened around her slender ankles. The male lead lifted her chin and made her look into the mirror. The sting made her shudder. Through her blurred vision, she met the young man’s unfamiliar black eyes. His usual gentle, moonlit demeanor had vanished, replaced by a clinging, gloomy madness that engulfed her, nearly swallowing her whole. The System’s alarm abruptly fell silent. Her heart pounded, and a chill crept down her back. His cold fingertips stroked the eternal blood pact burning against her chest, with tender, unhurried intimacy. The beautiful young man spoke calmly. “Baby... is this what marking looks like?” [Before you read] BG romance. The female lead is an alpha with no special appendages. Her body is anatomically ordinary for a woman; she only has pheromones and a spirit beast. The male lead isn’t an omega, just a normal man, though the female lead assumes he is. At heart, this is a fluffy comedy about two people talking past each other because they think so differently. It’s a niche self-indulgence, and the female lead is clearly written as a silly little cat, a goofy, sweet girl. If that’s not your thing, please don’t come in and tear it apart. Thanks.
