26岁的龙天豪与龙天贺是一对孪生兄弟,当年他们的父母龙守成与美智子,两人虽然相爱却因为门不当户不对被迫离异,龙守成带着哥哥龙天贺在台湾安守百年家业,美智子带着弟弟龙天豪回到故乡日本重新打拼,他们长得一模一样,然而性格迥异,哥哥龙天贺冷酷无情,弟弟龙天豪个性善良热情,两兄弟宛如善与恶的化身,一个是天使,一个是恶魔,他们对彼此爱恨交织,而他们同时爱上了一个女孩,自此改变了女孩的命运。

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.
