THE MISTRESS - It is not right
If there is a mistress stereotype, then Miss Noon, as she wants to be known, definitely does not fit it.
Soft-spoken and petite, she dresses simply and her only accessory is a watch.
Miss Noon, 21, who is from Vietnam, had to be persuaded to agree to this interview.
She is afraid of the possible repercussions after she shares her story, especially because her parents have been kept in the dark.
But she finally consented because she hopes that other women will not fall into the same predicament.
Miss Noon says in halting English: "It is not right. It doesn't matter how attracted you are to the man, but you should go far, far away the minute you know he is married."
She reckons it is the lack of a father figure - her own father had left her mother and three young children for another woman - that "made me interested in Charles".
"He was a good boss and he treated all of us very well. He was also very concerned about our personal needs, and sometimes, when a colleague was not feeling well, he'd tell them to go home," says Miss Noon.
"I have also heard stories of how much he loved his wife and would finish his work quickly so he could return home and take turns to prepare dinner for the family."
Mr Ng was, to her, the perfect man.
His only flaw, she says, is that he belonged to another woman.
"But as much as I tried to stop myself, I fell in love with him," she says.
"To avoid thinking or dreaming of him, and the hopeless situation, I tried to keep myself busy and started spending more time in the office."
That was another mistake.
"When I was in the office, I could literally 'smell' him. In the end, I found myself working inside his room so that I could imagine he was there with me."
Miss Noon says she feels "horrible" for hurting Mr Ng's wife.
"During the six months of the affair, I was kept awake by my guilt because I knew I had wronged an innocent woman," she says.
"When she came to confront us at the office, I felt even worse because she didn't kick up a big fuss. She was so hurt and angry, yet she was so mature in handling the whole thing."
Miss Noon hopes to quit her job once she completes her two-year contract.
"I cannot leave now because I need the money to support my younger siblings," she says.
Miss Noon avoided talking about Mr Ng, but says: "I would like to tell Madam Yong that I am so, so, sorry, and I am grateful she forgave me and did not insist that the company fire me.
"She will be blessed."
