She and her husband are expecting their first child, a boy.
"He is our miracle baby," says Madam Corina Sim excitedly, almost like a child who has been granted her wish.
She rubs her belly gently and looks to her husband, who wants to be known only as Mr Isaac, with a loving smile.
Madam Sim, 39, a Singaporean, says: "He gave me a new life, a chance to start anew. What is most important is, he loves me dearly for what I am, despite what I was."
Her past is a sordid one that she hopes her son will never find out.
She was a mistress to a businessman for nine years, during which she went through three abortions.
Her ex-lover eventually dumped her for a younger woman and kicked her out of the apartment he had initially claimed was bought for her.
He also took back her BMW and cancelled an insurance policy for her father, which he was paying for.
What was she left with?
The Panerai and Patek Philippe watches and a diamond jewellery set he had given her.
During the two-hour interview at the couple's four-room HDB flat in Sengkang, Mr Isaac remains by his wife's side, holding her hands in a reassuring gesture as she takes us through her past.
One that began in 1998, when her late brother chalked up gambling debts with loan sharks.
"Every two, three days, the loan sharks would be banging on our door, demanding payment," she recounts.
The harassment continued for almost a year until her widower father "nearly went crazy".
Madam Sim says: "We didn't know how to handle the situation. My brother went into hiding, but the loan sharks continued to hound us."
Then came the light at the end of the tunnel, she mutters.
The owner of the factory, where her father worked as a welder, offered her a way out: Be my mistress and I will pay off all the debts.
In return, he promised to take care of her and her father.
Madam Sim pauses for a few seconds, then says: "I was at a loss. On one hand, we really needed help; on the other, he was old enough to be my father."
Madam Sim was 23 and the man, 48.
"In the end, for the sanity of my father and for myself, I agreed."
It was the way out for the then sales promoter, who was earning $1,500 a month.
In return for her companionship, she was given $4,000 a month in allowance that gradually went up to $5,000. He also provided a two-room apartment in the west of Singapore for her.
NOTHING TO LOSE
Madam Sim also felt she did not really have anything to lose since she was single.
"It looked like a win-win situation," she admits.
"The first three years of our relationship were good ones. He showered all his love, attention and time on me. We travelled twice a year and I have been to all the countries in Europe and the main US cities.
"He also lavished gifts on me, even though I didn't ask for them," she says.
"To be honest, after a while I actually thought the relationship would work out and I would remain his lover until death do us part. I felt like I was married to him."
The only difference, adds Madam Sim, was that it was a relationship that "I could not share with my friends".
"You know, the photos that we took on our trips? I could show them only to my father," she says softly.
They settled into a comfortable routine where he would spend three nights a week at the apartment. There was only one confrontation with the wife during their affair, Madam Sim recalls.
"His wife came with their son and daughter-in-law and pleaded that I leave him.
"The son, a year younger than me, was the more hostile one. He called me a slut and told me, 'Watch it. When my father meets another woman who is younger than you, he will dump you. You are not the first and you will not be the last.'"
Madam Sim says: "How true. He really dumped me for a younger woman, who was working in his factory (in 2008).
"I was actually heartbroken when it happened and I went into depression."
It was also around the time that her brother died of cancer.
She smiles wryly, then adds: "Give him credit, he paid for the funeral expenses as a parting gift."
Madam Sim met Mr Isaac, 39, a civil servant, through a mutual friend at a church outing in 2010.
"I was wary back then about starting a new relationship, especially because I wasn't sure if I should come clean," she says.
"So I decided to keep it platonic at first."
After two years of being friends, Mr Isaac asked her: Can we take our friendship to the next level?
