Sister, I'm Pretending

Night Xiao, the CEO of Canstar Group, transforms into a shy and weak lamb to win over his childhood obsession, sister's best friend Xia Yutong. Suffering from a pathological obsession, he has loved Xia since age 16, but the six-year age gap and her status as his sister's friend meant they never crossed paths. To get her, he suppresses his condition, sheds his CEO title, and poses as a junior assistant to gain her sympathy and stay close. While seducing Xia with his charm, he ruthlessly eliminates all other men in her life.
