Is that series with the horrid disco-ball-looking ultimate weapon that gathers light and shoots out laser beams?
I last saw Catherine Hung in Mainland China's "Mystery Of the Palace" as one of the senior maids. Her role wasn't very big but she still looked very beautiful. Her husband was also in the same series.
Anyway, back to SOH. I hated Felix and Kathy together. I thought their characters were totally wrong for each other. Kathy was too clingy and immature and not to mention annoying. Felix only took her in out of pity and tried to accept her and move on from Amy. They were wrong from the start. Felix only asked her to take him back out of responsibility when Amy told him that she was pregnant. I don't think he ever loved her but he did care for her.
I got really annoyed when Kathy actually tried to seduce Felix, her sister's husband at the time, when he came to visit their son. But glad that she pulled out at the last minute. That was so wrong.
