Its actually a sparate in a way, (the kids from kiss me liar are friends w/ Angie) I really don't know how to post a picture here but there's a guide somewhere in the internet
Thank you so much for this it cleared up a lot (づ￣ ³￣)づ
there's a more updated version of that chart that Rhea_ballz shared btw (in case you want it) https://i.postimg.cc/9Ft0Yr0L/ZIG-aob-universe.jpg along with a generations tree that is very helpful for character relations https://i.postimg.cc/02gKCTCL/generation-tree.jpg (I also dw how to post an image so I hope these links work fine)
this manga is so cliche if they all happen in same timeline as other kiss me …. books why the wetup is like somtime modern with ph and tv and then carriage and horse shit bruh like this chapter for rain i get it but the setup looks historical
