Lorraine was born into a moderately well-off family whose parents ran a small restaurant. Lorraine and Ku were classmates in obscurity, and as early as 1993 when Ku signed on to become a singer from being an entertainer, Lorraine was his personal assistant who eventually stole his heart. According to close friends of the two, Lorraine is loving and righteous towards her boyfriend. Originally she had a good future in the record industry, but for the sake of Ku she willingly gave up her high salary and important position, humbling herself to be his personal assistant and taking special care of her boyfriend, and there are rumors that she used her private savings to buy new outfits for Ku who at the time earned little after just starting out. Moreover, Lorraine did not want to affect Ku's idol image, so for many years she has been his "invisible girlfriend" without complaints, quietly following him. And this long marathon romance has lasted 14 years so far with their relationship becoming increasingly stable. In 2007 they were photographed celebrating Valentine's Day in Japan with Vivian and Edmond, and last March they were photographed again shopping at a furniture store and looking at properties.
