@Kodama
Apart from the obvious trope, I'm going to assume that at the very least Lilith knew, hence the kiss, and that it would be easier to just ignore the peeping tammy.
I really hope that they intentionally showed her that scene. Abel was shown to be able to sense the world's best assassin mages hiding in trees so there's no way he wouldn't be able to notice a random student closing in on them.
@starburst98 Usually the raws (or the novel if it exists) for the mangas I read are advanced enough that people add tags even for something that happens in chapter 50 with the English scans having only 1 chapter, at least that's the case with mangas I read on mangago but it might be different elsewhere and also I realize that some English scans are caught up to the original material so we can't have tags for future events.
Anyway, thank you for your reply
This is the same character that was able to recognize that a flying robot was following him, but couldn't recognize that a clumsy girl that fell on her ass outside his room is peeping on him?
This weird opsec lapse is a little out of character for Abel, not to mention Elize being dumber than a sack of bricks blabbering all about it to a random girl friend.
