their son will date the main story couple's child
Won't they have another baby?
Josh appears in "Kiss me liar" at the same time you see him meet Yeonwoo here. He later sends Dane to help Yeonwoo. In the extras you see his two sons becoming friends with Spence, the first son of the Pittmans.
Josh's sister Emma it Keith Pittman's secretary and has a crush on Yeonwoo.
Yeonwoo ( MC of KML, beta turned omega) was Keith Pittmans secretary (including managing his affairs with all those actresses), who had a crush and Keith, got pregnant, marked him and ran away.
Chase is Grayson Miller's younger brother.
Grayson Miller is Keith Pittman's close friend.
Keith Pittman (ML of KML) is the boss of the production firm Chase is shooting the movie for. He is from an extremely rich and powerful family. And he is the author's trash king, so I'm surprised you forgot Keith.^^
Who are they and how are they related from the other story guys I have forgotten the kiss me liar ( that's where they are from right?
