The divorced couple in Korean drama Emergency Couple are always seen quibbling and in one scene even get into a massive fight.
The series' leading lady Song Ji Hyo says the key for couples to getting over tiffs is to get physical.
Not get into physical fights like she did in the show, but to have "skinship". It is a common term in Korea to describe physical touch.
Song, 32, flew in from Seoul on Thursday with her co-star and onscreen ex-hubby, actor Choi Jin Hyuk, to promote their romantic drama Emergency Couple.
They play a divorced couple whose paths cross years after their divorce and meet as medical interns at a hospital’s emergency room. Emergency Couple is currently airing in Singapore.
Choi, 28, says couples working in the same workplace or industry could have a good romantic and professional relationship, as they would understand the nature of each other's job.
However, he has some reservations about dating an actress.
He explains: "I'm a traditional guy. I won't like male fans looking at my girlfriend."
After the media interviews at the Pan Pacific hotel, he and Song met fans at shopping mall Square 2 in Novena.
They are also the stars of the ticketed Emergency Couple fan meet held at Kallang Theatre on Friday night.
The amiable and fresh-faced Song is best known as the smart and brave solo female host on popular variety show Running Man. She was last here at an October fan meeting with her Running Man co-hosts.
The hunky baritone-voiced Choi has taken on the roles of ambitious older brother Kim Won in idol drama The Inheritors (2013) and the heartbroken demon Gu Wol Ryung in the fantasy series Gu Family Book (2013).
