As a Nobody, I Just Want to Get Stronger

[Unconventional harem heroine + background character + transmigrate into a book + System + elite academy + everyone has a one-sided crush] After transmigrating into a cheesy elite academy novel, Zheng Jie became an invisible scholarship student and background character who didn't even have a name in the book. No main plot, no villainous missions, no romantic entanglements. Zheng Jie made her decision on the spot: lie flat and coast until graduation. She wouldn't steal the spotlight, cause trouble, or get involved in the original story's tangled romances. She just wanted to quietly remain in the background. But could someone explain why had the plot gone completely off the rails? Xia Yuteng, the original heroine, a gentle little flower, blushed at the sight of her and avoided meeting her eyes. So why was her closet full of Zheng Jie's intimate apparel? Bai Yuanyuan, the original story's proud, aloof heroine, had transformed into a clingy cuddlebug, chasing after her every day to shower her with affection. Bai Yan, the arrogant and wicked young heir, was a fierce wolfdog to the outside world but her loyal puppy in private, sticking to her side so closely it was downright outrageous. Xie Mian appeared refined and gentle, but was actually plotting at every turn, quietly drawing her into his tender trap. He Lingzhou was a gloomy, possessive younger man with a twisted streak. His obsessive desire to possess her was dark and intense; his eyes held room for no one else, and he wanted nothing more than to hide her away and keep her all to himself. Su Wangheng, the noble and aloof head of a wealthy family, seemed distant and indifferent, yet made an exception for her alone, silently clearing away every obstacle in her path. (Everyone has a one-sided crush on the heroine, and there are more than just the characters in this blurb.) (The heroine is carefree and strong.)
