Actress Kyung Soo Jin participated in a series of interviews about the tvN drama “Mouse,” which aired its final episode last week. In “Mouse,” Kyung Soo Jin played Choi Hong Joo, a producing director (PD). She was involved in a romantic relationship with Sung Yo Han, the character played by Kwon Hwa Woon. Kyung Soo Jin said, “Kwon Hwa Woon’s character was very cold at the start of the drama, like a psychopath. He wasn’t actually a psychopath, but someone who is very rational and logical at heart, so he came off as very cold. It was a bit difficult for me. Usually actors will share emotions with each other in romantic scenes, but Kwon Hwa Woon was so good at playing his character that it was like acting opposite a tree. I couldn’t exchange emotions at all. I had to take the lead, a softer approach, so I think it came across as more maternal than romantic.”
