AH-WAI and Ah-wan (not their real names) are a loving couple in their 20s. They live their lives around two sons, and AIDS.
The husband, Ah-wai, tested HIV-positive five years ago after an operation. Ah-wan, a few months pregnant with their second son, tested negative.
But they were determined to save their relationship, which has lasted 11 years.
The two had as teenagers doing summer vacation work. They were married two years later and had their first son seven years ago.
At 23, Ah-wai went into hospital for an operation. He felt scared and numb when the doctor told him he had tested HIV-positive.
''It felt like the end of the world,'' his wife said.
''I remember hearing the words but not really understanding what it all meant.'' Nowadays, they watch their children play and wonder what the future holds for the two young boys.
