My Sister of Eternal Flower (Traditional Chinese: 花花世界花家姐), is the title of a Hong Kong television drama starring Charmaine Sheh, Raymond Lam, Ngo Ka-nin, and Toby Leung.

One day Zhang Sum ended up in the hospital, and his spoiled grandson Hugo (Raymond Lam) took over the company.

However, Hugo was incapable and loses control of the company to Mike (Ngo Ka-nin), a genuinely skilled manager.

At the lowest point of his life, the only one that backed him up was a mentally low-IQ girl Fa Lai-chu (Charmaine Sheh).

Hugo would bounce back and have to decide between the intellectually disabled girl Fa and Agnes (Yoyo Chen), the beautiful perfect model who didn't stand by him enough.
