The Jujutsu World's White Moonlight

When Lan Imaizumi was seven, her mother married into the Zenin family and became the second wife of a Zenin clan member. From then on, Lan's surname changed from Imaizumi to Zenin. As the Zenin family's younger young lady, she lived a life of constant rejection in a clan that valued bloodlines and innate cursed energy above all else. Her cursed energy was weak, she was sickly, and apart from her pretty face, she had nothing. "Lan, you must always stand three steps behind me and wait for me to call you back. Understand?" her young lord once said into her ear. Once she understood that those without power would be bullied, she decided to make a contract with the Demon of Love in exchange for strength. After the contract was successfully signed, a line of text suddenly appeared in Lan's mind: Main quest unlocked: Become the White Moonlight of the entire jujutsu world. Zenin Lan: I think you're asking the impossible. I'm out! Demon System: Get back here! Give me every bad ending! You can't log out until you get all the bad endings! Please note: 1. The heroine is a Mary Sue with many admirers, and the ending is 1v1. 2. This is not a lighthearted, comedic, indulgent romance. It is more of a serious drama, with both sweet and angsty moments. 3. A crossover, with plenty of characters and content beyond those in the title. Theme: True love is pure and sincere, without ulterior motives
