If you actually talk to Yu Hae-jin, you’ll be in love with his charms: he’s an actor with kindness and kindness in a few short conversations. I throw a gag at the right place, and sometimes I make a laugh with the wrong words. Even though he is a top star, he was surprised at the praise, and he had a delicate consideration to look at others more than me. The film "The Wrestler (director Kim Dae-woong)" appropriately utilized the charm of Maseong that Yu Hae-jin had. "The Wrestler" is a comedy film centered on his son, Yu Hae-jin, who has been transformed from a former The Wrestler to a professional housekeeper for 20 years. Gwibo draws a story about a peaceful daily life being overturned as he becomes an unrequited love opponent of his son Sung-woong (Kim Min-jae), "girlfriend" Ga-young. Yu Hae-jin, who is under the affection of Lee Sung-kyung, is bound to laugh, but some of these settings also have a voice of concern. Yu Hae-jin made a line with Lee Sung-kyung in the play, saying, "It is not romance but unrequited love." Also, he emphasized 'The Wrestler' as a family film, not a melodrama.- Drawed as a Mars man. "That's weird. Does it make sense? Not Masong. It's just that it's drawn. Hahaha."- The director casts him as a charming person. "I think it's good for this age, and I think those things are right. I think it is because I am an actor who can learn and learn that my son and chemistry can come out, and I can do Aerobic. "- Aerobic scene is a laughing point. "The actual Aerobic scene was really tough. (laughing) It was also my idea to get inside and take a break. I wish there was one such hard scene, doing so much for my son, and doing so."- What kind of son was actually Yu Hae-jin? "It was a bad child. He was a rotting child. There were many things rotting inside him, but he opposed his parents to play. I understand now, but at that time, I was looking at 'why do not you let your son do it?' Now I think 'it would be difficult to accept it easily'. I’ve been rotting a lot and rebelling a lot in that part. That’s all. Of course there are many others. I wish I had seen my son go well, but he would have been fine, but my mother died too early, I don't think he was a good son as a whole."
