The Disobedient Supporting Female Character Awakens

Just putting up an advance notice for "The Junior Sister in a Bubblegum Novel" Jiangjiang is way too tame. Unable to bear the agony of having her story locked, Jiang Tang went to Fenpaopao in a fit of pique. She had just finished laboring over the outline when she transmigrated into a book. As a typical bubblegum-style harem novel, the junior sister in the story is supposed to be thoroughly doted on by seven men. Jiang Tang looked at herself, transmigrated as the only female side character, and panicked. Help! Am I seriously going to have to fight the heroine for the men?! System: No, your mission is to make sure the heroine doesn't get involved with the men below the neck. Jiang Tang: Got it. You're the Jiangjiang content reviewer. So Jiang Tang fought on the front lines to keep the world wholesome. She stuck to the heroine all day long, even refusing to leave her alone when it was time to sleep. The junior sister was warm and soft, and aside from having no meat on her chest and being so tall she took up too much of the bed, she had no flaws. Until one day, the junior sister invited her to take a bath together. Jiang Tang watched him walk toward her half-naked, his fingertips lightly hooking into her collar, and panicked. Help, the heroine's about to make a move on me! System: It's okay. You're not a man, so you can get involved with the heroine below the neck. Jiang Tang: Wake up, System. There's no heroine. The junior sister is a man, damn it! &%#*@ (The author discovered that she actually likes writing spicy stuff, so unless something unexpected happens...) The actual blurb: Xia Yao awakens to her own consciousness and discovers that she's the vicious female side character, forcibly made stupid by the author. The heroine is Xia Xi, the gentle, kind, and considerate top student who was taken in by her family. The substitute older sister adopted after Xia Yao went missing. The real daughter, missing for ten years, returns. Her parents are away, her brother is devoted to the fake daughter, and he's even planning to develop a pseudo-incest relationship... In the story, three men fall for the fake daughter, creating a bloody battlefield of rivalry, while Xia Yao... Driven mad by jealousy, she tries to harm the fake daughter, accidentally falls from a building, and dies a tragic death as the result of her own actions. But now... Xia Yao: My brain is finally working. Goodbye, trash male leads. All I want to do is study. That day, she and her friends angrily cornered the heroine in the bathroom. Word got out, and the heroine's three men rushed to the scene, determined to expose the vicious side character's true nature! They knocked over the sign saying the bathroom was under repair and kicked open the door. "You can't even solve this problem! How can you face your parents or your teacher, who's worked so hard to teach you?" The girl sat on the sink with her legs crossed, smacking the mirror with her palm over and over, looking utterly exasperated. The mirror was covered in mathematical formulas. Xia Xi's face was streaked with tears. "Sob, sob... I've let them down..." The male lead who's sweet on the outside and scheming within: Xia Yao, it's late. Come home with me. The male lead who's scheming on the outside and sweet within: Xia Yao, you started a cram school without telling me. You're playing favorites, hmph.
