uhh better late than never? haha!
It's not a spin off, both are manhwa adaptions of stories that are part of the same universe, written by the same author. Some characters appear in both.
Both are parts of different series, well only one is part of a series so far, the Millers at the moment have 4 novels and one to be released soon. Seems she wants to get the Millers done first before Angel and Keith's half siblings. And there are also 3 more stories that are part of this universe.
They showed Chase only once in KML, but well he looks kind of strange.:D KML and KMUYC are drawn by different artists, but are witten by the same author as I mentioned.
DID EVERYONE KNOW BUT ME?! YOU GUYS ARE FAKE!!! WHY WAS NO ONE TALKING ABOUT THIS BEING A SPIN OFF?! I DIDNT EVEN FIND OUT UNTIL I REREAD KISS ME LIAR AND THAT WAS TODAY T-T
Seeing the timelines clash is so satisfying -u-
Also Chase Miller in kiss me liar and in kiss me if you can is COMPLETELY different! It’s weird seeing chase look so hideous…
And they made Pitman extra fine on this lol
