chase and Keith have a like customer x CEO type of relationship, so they both respect each other in that way, however chase is not really deep into the story compared to his older brother Grayson, who is a close friend of keith. Yeonwoo and Josh are good friends, they often help each out, and in side stories even gets invited to Yeonwoos baby shower (KML side story 4)
Keith Pittman is the owner of the production firm, which produces the movie Chase is currently shooting. And Keith is also a very close friend of his older brother Grayson, since childhood. So those two are aquainted and Chase his currently working for Keith, that's all.
Josh met Yeonwoo during a party and he helped him, also got his friend Dane to help him. They became friends, and their children also became friends.
I actually think that Keith can't stand Josh and Dane.^^
He is not evil, he is just his crazy self.^^
Grayson's way of helping can be the opposite of help, and he is not aware of it. And his logic can be pretty weird sometimes. Chase is a victim of that.
But Chase is not willing to release pheromones. So if Grayson doesn't make sure he does, their father will take care of that, and I don't think that Chase is eager to deal with him.

I only realised halfway through that these stories were linked ^^^ can anyone tell me what correlation josh and chase had to the kiss me liar story?? All i remember is josh helping the yeonwoon, and emma having a crush on yeonwoon
