This is not Ji Sunwoo (played by Kim Hee-ae)'s son, but his friend.
He was born in 2004
Jung Junwon: Is there any job vacancy?
Friend: Drama filming
Jung Junwon: What about the AV that your mother stars in?
-I bet he's going to be edited out from the last episode of The World of Married Couple...
-Why does he drink that much...?
-Hmm? He started his career back in elementary school, right? He looks really familiarㅋㅋㅋ I can't believe he posts things like that on his Facebook, did he not think that it could cause a controversy?
-I bet his parents are going to be really sad to see those posts...
-He doesn't even have what it takes to be an actor... Skill and visual wise.
-Whoopsies, seems like we're not going to see his face on TV anymore from now on...
-Hul, I went to the same middle school as him...ㅋㅋㅋㅋㅋ
-I'm not that surprised with him smoking and drinking alcohol, but the way he makes fun of his friend's parent in the first picture is way unforgivable...
-He's not going to last in the industry anyway. He would disappear from the screen in a couple of years, he's not a good actor.
-Doesn't that mean he's still an underage...? And yet he drinks and smokes...? Oh Gosh
-Is he a gangster or what??
-Okay bye~~
-Kids these days are so much scarier than I thought...
-Acting is not for you, kiddo.
