He said, "I always contact the actors from 'Triangle' and have drinks with them once in a while. �We don't only talk about acting. �In Siwan's case, he contacted me saying he was having such a hard time while filming tvN drama, 'Misaeng.'

During times of rest, I get a ton of calls saying how hard a time he's having. �I don't know why he calls me to say he's having such a hard a time, but since we live nearby, we don't talk about acting, but say things like, 'Let's eat,' and, 'I want to drink quickly.'

I even met up with Shin Seung Hwan, Lee Yoon Mi, and Shorry J not too long ago and ate with them. �When I do a production with people, I consistently keep in touch with them and meet up. �I don't think we talk about personal things."

Meanwhile, 'Spy' will start airing on January 9!
