It's Perfectly Normal to Disguise Yourself as a Boy at a Noble Academy

I've prepared double-flash badges of the heroine and two holographic ticket stubs as free gifts. I'll periodically hold giveaways for the remaining stock! Blurb: Ye Chenxi transmigrates into a book. She becomes the villainess in a classic story set at an elite academy. In the book, the original heroine is a Cinderella who gets into the school through excellent grades, while she is the stepsister of F1, though they share neither parent. Because she was frail and sickly, she was dumped in the countryside and raised like a boy. After returning, she becomes insanely jealous of the original heroine and tries to frame her at every turn. Ye Chenxi, who has transmigrated into the story, has this to say: Stay out of trouble. None of this has anything to do with me. [System: Host's life is in critical danger. Approach the Chosen One as soon as possible to gain life points.] Ye Chenxi: ?!! Then of course she's going to win over... the original heroine! * She works hard to take care of the original heroine, while making sure to fleece the F4 whenever she can. For instance, at home, she acts as meek as a mouse, never competing or making demands. Every day she prepares warm milk for F1 and unfailingly says good morning. Over time... one day Ye Chenxi forgets to suck up to him, and her cheap older brother actually blocks her at the door. "Are you feeling unwell today?" Ye Chenxi: ? She strives to become F2's confidante, keeping him company whenever she finds him lonely and helping him come up with plans to pursue the original heroine. One day, she happens to catch F2 chatting with the original heroine. Ye Chenxi silently turns to leave, only for F2 to call out gently, "A Xi, where are you going?" Ye Chenxi: ... (Furious at him for failing to get the hint.) She works hard to be F4's right-hand girl, accompanying him on wild rides all over the country on motorcycles, even landing in the hospital. One day, Ye Chenxi merely chokes on a sip of water, and he anxiously asks, "Are you okay?!" Ye Chenxi: ... How about some plum candies? She becomes buddies with F3, the playboy, and introduces him to all kinds of beautiful women, only for him to grab her and say, "Why don't you understand how I feel? I don't want anyone else's contact information." Ye Chenxi: Huh? Ye Chenxi: Wait, have you got something wrong? I'm a guy, okay? Everyone: Stop pretending. We figured it out ages ago. Content warnings (please note): 1. The heroine is a heartbreaker. Everything she does is in service of winning people over. If you can't accept that, please don't read. 2. Otome-style romance. The main story has an open ending, with different endings in the bonus chapters. 3. The original heroine and the heroine are very close. If you don't like that, don't read!
