Yes!!! I’m pretty sure Joshua’s story takes place where yeowon is still just Keith’s secretary!!
Fuuuuuuuk I'll have to re-read cause I can't remember any side character. I just remember tha MC, ML and the Blondie.
It is the same universe! Apparently there are a few different stories by this author in the same universe. Soon there will be one between Dane and Grayson ("Desire Me If You Can", as you mentioned). The main characters in this story are Chase (Grayson's brother) and Josh (Emma's brother/the single father that helps Yeonwoo escape and introduces him to Dane).
Yesss, they’re in the same universe. I was surprised when i saw them too!!
Joshua is the one that helps yeowon escape from Keith
So it's been a while since I read, Kiss me Liar, but are they, Desire me if you can and this story connected (like same universe, connected character stories etc)
