"Kiss me Liar" is not the main story to this, it's same universe, but it doesn't belong to the "Kiss me.."(Angel and his 5 children from different DA) or "....if you can" (Miller family) series. They don't appear in KML. Only the daugther in a not to manhwa adapted side story. But 2-3 known characters will have a short appearence in Kiss the scumbag.
Another spin-off? Which chapter did they appear on kiss me liar??
