I whole-heartedly agree with this… this is definitely not beginner-level reading. Things are so over the top it’s hard to tell if one understood the meaning of the dialogue right or not; some jokes rely on references to proverbs or poems that a learner would be very unlikely to be familiar with, and even sometimes they are tweaked which makes it incredibly hard to google.
Not the book’s fault, but I’m also really disappointed about how low quality the digital version of this manga is. It feels really unfair that I got charged basically the same price as a new copy of the physical version for it.
