This entire manga so far has been about shouta MC and his "old hag" crush (that looks young cuz manga obviously) and that's to be expected from the title really...
But all the other characters are more interesting than the main two (also fits better with MC)! Well other than the father, he's a piece of shit. And seeing the better characters running around just makes me feel even worse knowing the author wont put them to use but will just keep making chapters where ML & FL sit around crying about how fucking dumb they are.
What I'm saying is, this is the kind of manga where the spinoffs would be better than the main story, because the main story is BORING.
