I Became the Big Shot's Nanny [Book Transmigration]

This is badly written and goes off track. Read at your own risk. Blurb: Qiu Lu woke up one day to find that he had transmigrated into a book as its vicious male supporting character. He had faithfully served the powerful male lead as his caretaker for ten years, only to end up pinned to the ground and forced to crawl like a dog and call him Daddy. But he deserved it. The original character had harmed the male lead's mother, killed his father, and caused the male and female leads to be separated by a misunderstanding for five years. In short, he was the nastiest, most stubborn obstacle on the male lead's path to godhood. After he transmigrated into the book, Qiu Lu imagined a hundred ways to die without looking too pathetic. Then he saw the powerful male lead. Qiu Lu: Huh? The little boy in front of him, with fluffy hair and chubby cheeks, looked no more than eleven. He didn't seem all that scary! Even if the kid would kill him in a few years, he might as well enjoy himself while he could! So Qiu Lu really did dutifully become the young male lead's caretaker, only to watch the story go wildly off course... The male lead once again claimed he couldn't sleep and snuck into the bed of his villainous male supporting character. Qiu Lu finally couldn't take it anymore. He pushed away the boy who had expertly buried his head against Qiu Lu's chest and snapped, "Fang Huo! You're a big kid already. Why are you still so clingy? Am I your mom?" Fang Huo's big eyes quickly filled with tears. "No. Lu Lu is the person I like most." A wolf-like top who pretends to be harmless, ruthless to others but obedient around his beloved, Fang Huo x An innocent bottom who seems like an unfeeling, straight-as-an-arrow guy but is actually gentle and kindhearted, Qiu Lu Age gap: The top is younger, four years apart One-on-one romance, happy ending A few notes: 1. This is a relationship where the characters grow up together, and the story spans a long period of time. 2. Also known as "My Scheming Little Brother Falls in Love with Me," a light, fluffy, rambling story. 3. There is a reconciliation after a breakup, but it's basically there for fun. Theme: An inspiring story
