he first appears chapter 29. i don't think he appears again in the main story after that one appearance.
he is first mentioned in chapter 27 by his sister. pretty sure he only had 1 kid at that time.
and he appears again in the side stories (starting from the first chapter) but i don't believe he has a significant role and neither do his kids. i haven't finished the side stories though so I might be wrong about how much of his story is told in kiss me liar

so i read spoilers and its mentioned he has 3 kids in the Kiss Me Liar side stories hehe, apparently in KML chapter 48 when he had the call with Yeonwoo, there was a part omitted from the novel where he mentioned he was pregnant with the third kid
I guess it just wasnt mentioned in Kiss Me If You Can since the epilogue + side stories were earlier in the timeline
Did you know in which chapter josh from “kiss me if you can” in “kiss me liar” appear? I would like to read his story especially when they mentioned his 3 kids. Thank you
