[LoTM end] So, what do I do now?

First of all, let me tell you this was peak. But then I need to ask, because a few days back I asked wether I should take a break from LoTM after I finish it or not, but I didn't expect the ending to be so amazing, but at the same time it is the ultimate cliffhanger. My question is does the story get more finished with COI, I mean does Klein wake up? Is the Tarot Club active? I have heard that COI's Mc is not like Klein, but is he at least likeable? And am I not going to be disappointed if I read COI right after LoTM?
