I Transmigrated as the Older Sister of the Angsty Novel's Bottom [Book Transmigration]

[Updates will resume after the college entrance exams] Jiang Yueya transmigrated into a melodramatic boys’ love novel set at an elite academy. Not only that, she seemed to have become a wicked supporting female character. In the novel, she was the evil older sister of a sickly, unhinged shou. Ever since her family adopted him, she had abused him and relentlessly targeted him. In the end, she met a tragic fate. No way! She had to change her fate! If she couldn’t avoid interacting with him, she’d just be a good older sister and do her best. She only hoped that he would spare her in the future, for old times’ sake. So Jiang Yueya made up her mind. When her father led a filthy little boy to the front door and the relatives all objected, Jiang Yueya took his hand and welcomed him inside with a kind smile. When he was excluded and bullied by the family, Jiang Yueya stood up for him without hesitation. When he was often ill and the family treated him like a burden, Jiang Yueya stayed by his side, never leaving him. A few years later, the story began. Her younger brother pinned her against a wall in front of the gong. His eyes curved, possessiveness hidden within them, his gaze infatuated and wild. His warm breath brushed her ear. “Big Sister, stop treating me like a child.” Jiang Yueya: ??? Wait, isn’t your gong over there? * Li Ya had been unlucky since birth. A madwoman for a mother, a scumbag for a father. Even after a chance event led to his adoption by a wealthy family, he still endured their contempt and neglect. There was only one person who treated him differently. His older sister. She had always greeted him with a kind smile, cared for him, and protected him. Li Ya thought she was like the sun, brightening his filthy world and bringing his heart back to life, teaching it how to beat again. What should he do? He really, really loved his big sister. He loved her so much that, whether it was the stars, the moon, or anything else, he would offer her whatever she wanted, one by one, until she relied on him so much that she could never leave him. * Reading guide 1.
