Kai-hung's father had had a stroke, his mother had walked out, and every evening he went to work in a KTV parlor, where he earned NT $ 8000 a month. Immersed in a nightlife of singing and dancing, he had no interest at all in his school work.
原來凱宏的爸爸中風，媽媽離家，他每天晚上要到ＫＴＶ店裡打工，賺取八千元的工資，日夜顛倒、歌舞迷醉的生活，使他根本無心於課業。
