This story is more or less between 3 or 6 years (we don't know for sure) after Kiss Me If You Can. Grayson is the last one of the Miller siblings to have a "destined" partner (we don't know about Grayson's twin sister, Stacy, but Chase, Bliss, Nathaniel and Larien, this one with multiple wives, already have a lover). Kiss Me If You Can, Kiss Me Liar, Kiss The Scumbag and Desire Me If You Can manhwas are all adaptations of finished novels which share the same universe and characters.

WHAT CHASE AND JOSHUA ARE ALREADY MARRIED IN THIS MANHWA??? kiss me liar wasn't even finished yet, and how come there's nobody's talking about this
