The loving couple, Long Shou-cheng and Michiko was forced to separate due to differences in their family status. Their twin sons, Long Tian-hao and Long Tian-he were also forced to separate from each other—Long Shou-cheng taking his elder son, Long Tian-he, and remained in Taiwan to manage the century old family business; Michiko took their younger son back to her homeland Japan to build a life from scratch. Now the twins are 26 years-old, identical in appearance, but extremely different in personality; the older being cold and ruthless, whereas the younger is kind-hearted and passionate. Each brother seemed to represent good and evil, one an angel and the other the devil. It was a love-hate relationship between the two brothers. Yet when they fall in love with the same girl, they also changed the girl’s fate from that point on.
