Comments: I growing more and more concerned about Lunmei Kwai's career, although she was excellent in Flying Swords of Dragon Gate.

Summary: Bao sacrifices herself, becoming a butterfly, to save her sick fiance and discovers in the process how true their love is.

In an unspecified time when epidemics run rampant, botanist Yan Guo (Aloys Chen) and his fiance-assistant Baobao (Zhang Yiyan) move to Moon Island, a nature reserve, to research the curing properties of rare plants. As is customary, they pray to the magical Eros Tree to cement their love, unaware that they have to undergo a severe trial, in which Baobao must remain unseen to Yan for three years in exchange for his life.

Baobao transforms into a butterfly, and like the Little Mermaid, she watches two other women – horticulturalist Bailan (Kueh Lun-Mei) and journalist Yang Lin (Gigi Leung) — court her lonely boyfriend, but cannot speak out her feelings. Cheung does not exploit the plot potential to create a melodramatic love quadrangle. Instead, he opts for a more down-to-earth, feel-good emotional arc by describing how Yan’s platonic friendship with the two women motivates a breakthrough in his research. – via reuters.com
