I don't want to waste my home space and money on more frequent purchases.
This is also one of the reasons why I don't purchase that often. Also, yes—comics and mangas aren't only stuff for reading, I also make some of the panels as a reference so yeah it's pretty much usable, but just to avoid scolding, I just keep my purchases, as much as possible, in secret so that my mother can't waste time scolding me hahahaha
Sorry for the late reply, I'm away from home on a trip.
Luckily I don't hear my parents scolding me, because I live with my partner :D. So she's the one complaining, but for different reasons xD. You can also lend comics to someone to read.
