In DIF 4, Maggie Siu plays as 2 people. She plays as Kong Tze Ching and her long-lost twin sister, Tze Yiu who are both Sunny's sister. Tze Yiu turns out to have a mental problem and that caused some problems. Due to that, she had to sneak into Kong Tze Shan's (Sunny Chan) and Tong Sum Yu's (Lee San San) wedding. In order to prevent people from recognizing her, she locked Kong Tze Ching in the bathroom and went into the wedding pretending to be her.

Unfortunately, they eventually found out that she wasn't the real Kong Tze Ching. The police tried to seize her but she begged them to let her stay to see her brother's wedding.

It was heart-breaking when she was standing on stage begging to stay for the wedding.


While taking pictures and cutting the wedding cake, Tze Ching suddenly had hallucinations that Tong Sum Yu (Lee San San) was her past boyfriend whom often abused her. She was really scared of him and when she saw him, she took a knife and stabbed him. Since it was a hallucination, the person who she actually stabbed was Tong Sum Yu.

Rushed into the hospital, Tong Sum Yu was immediately taken to the operation room. Unfortunately, she lost too much blood and died there.

It was unexpected and a tragedy of Tong Sum Yu's death. After all the things they went through, they have to be separated on their wedding day. I felt horribly sorry for Sunny because the person who killed his wife was his sister.

This post was suppose to be written quite awhile ago due the other post (here). While writing this, I didn't felt as much as I did back then cause it have been awhile since I've finish this.
