It's about a Japanese woman who went to HK for her father's business trip. There she meets a HK mafia and later she and the HK mafia accidentally meet a Japanese man who looks exactly like him. That Japanese man works for the woman's father's company but he doesn't know the girl is his CEO's daughter.

The girl and the HK mafia fell in love with each other but the mafia guy died before he tells her he loves her. Before he dies, he accidentally met that Japanese guy that look like him and asked him to go to meet the woman and hand the woman what he described to him as a present.

The Japanese guy went to the woman's room in the hotel, but the woman thought that he's the HK mafia, so she confessed her love to him and they slept together. The Japanese guy is confused, so in the morning, he left without saying anything. The girl wakes up and later learned that the mafia's dead.

She went back to Japan and later learned that she's also pregnant, causing her to has to get married-just to avoid rumour. So she decided to pick a Japanese man in her father's company as her spouse. The man she pick is the Japanese guy that look like the HK mafia guy-she pick him without knowing that that Japanese guy is the same guy they met in HK and is actually the one she slept with in HK.
