Not necessarily important to read Kiss Me Liar before Kiss me if you Can. Basically a shared universe. I forgot what the family tree looked like sooo. It's just that there are some snippets and events that overlap between the stories.
These details can connect some dots in Kiss me if You Can, especially with the pheromone cases. Josh and Yeonwoo have interactions multiple times in Kiss Me Liar as well and there are also scenes here where the children of both couples interact a lot.
I have read Kiss me Liar first since it's been years before KMIYC, reading it first did give me a few context but not so much. I'm just here for Josh and Chase's kids tbh, considering that there isn't much of them from the novel (except during the extras)
Thank you so much ! If that's the case I might read "Kiss me, Liar" to find Josh in some chapters, cause it's funny that the two stories do have some sort of interaction.
Glad to help! I do have to warn you that this story is quite a roller coaster ride compared to KMIYC. It gets really toxic, especially with their decision-makings and how they handle their issues. Enjoy the read if you ever decide to do so! ヽ(￣▽￣)ノ
Can someone explain how "Kiss me if you can" and "Kiss me, Liar" are related in the lore ? Cause I don't get it some people say they had to read "Kiss me, Liar" before reading "Kiss me if you can" and I'm confused ╥﹏╥
