Actors So Ji Sub, Jung In Sun, Son Ho Jun and Im Se Mi attended a press conference to promote their new series My Secret Terrius in South Korea.

The romantic comedy tells the story of a secret agent-slash-babysitter (Ji Sub) and his neighbour (In Sun) who team up to get to the bottom of a conspiracy. Ji Sub talked about his experience working with kids, saying, "It’s really hard to raise two children. Mothers are superwomen!"

To prepare for his role, he went on a diet, studied his character, changed his style and took martial arts classes. The director praised his portrayal, saying, "Even Matt Damon could not do a better job."

To prepare for her role as a single mother, In Sun did a lot of homework, including observing online communities for mothers in order to better study her character.
