Having played the female lead opposite a number of leading men, Rui En said that her favourite couple role was with Elvin Ng.
According to an article in The New Paper, she said: "Every time I work with a different person, there is new chemistry. But if I have to choose one, it will be Elvin.
"Our own fans are very supportive of us together on-screen and it's fun. I am surprised that 'Ruivin' has become a thing now."
The term 'Ruivin' was coined several years ago by fans after the actors' pairing on The Dream Catchers gained popularity.
The duo are so popular they have bagged the Favourite Onscreen Couple Award at the Star Awards two years in a row.
