Honestly, if Maki doesn't accept Liz back I wouldn't be surprised.
I would be very surprised if that happened. Maki already expressed that she hoped she'll be "worthy" of Liz some day, if the translation is accurate. This was post-cheating mind you. I'm a bit conflicted, because on the one hand it would be really, really cathartic to see Liz experience some kind of consequence from her actions and to see Maki actually stand up for herself. On the other hand, this will be cemented as a 9/10 comedy for me if everything gets handwaved in a generic ending. Either way, it'll be great! I can't believe I doubted this work in the beginning.
