Jian Chenyu has been renowned among the second-generation elite circle since childhood for her excellence, exuding an aloof, moonlike grace. Upon starting school, she instantly stole Sang Shian’s title as the campus belle, captivating the hearts of countless innocent boys and girls. She is Sang Shian’s roommate—and also the person Sang Shian despises the most. One day, Sang Shian accidentally discovers Jian Chenyu’s browsing history of lesbian adult films. At the same time, she learns that the Jian family is arranging a marriage alliance for Jian Chenyu—with a young, accomplished, wealthy, and considerate man—who happens to be Sang Shian’s own older brother. The mere thought of having to call Jian Chenyu "sister-in-law" for decades drives Sang Shian to a decision: she will seduce Jian Chenyu, lure her off her pedestal, and ruthlessly expose her sexual orientation. There’s no way she’ll let Jian Chenyu become her sister-in-law. The moment her friend request is accepted, Sang Shian dons a catsuit with a skirt barely covering her hips, kneeling suggestively in front of her phone, swaying her tail at Jian Chenyu: *"Sis, I like you so much… I want you to fuck me senseless every night."* Regret hits Sang Shian immediately after sending the message, and she scrambles to recall the video—until Jian Chenyu, notoriously indifferent, replies: "Pull the clothes lower. Let me see your tits first."Sang Shian thought she was playing her role flawlessly. One day, she’s a helpless princess forced to perform barely clothed; the next, she’s a saintly elf whose unsated tail burns with desire—all to bewitch Jian Chenyu, who even rejects the marriage alliance with Sang’s brother in a fit of lovesick recklessness. Mission accomplished. That night, Sang Shian logs into her alt account, executing a swift breakup and block. Yet, within two hours, Jian Chenyu knocks on her door. Sang Shian’s pupils shrink in panic—she slams it shut. But Jian Chenyu is faster, slipping inside. Cool fingertips brush her face as Jian murmurs: *"Running away, kitten?"* *"Were you drinking again?"* *"Do I need to lock you up to make you behave?"* Sang Shian: *...I’m doomed.*
