This is such a good story. If you like or are even the slightest bit interested in art, I would highly recommend reading this. I feel like it covers so much that artists deal with; the stress, learning new skills, dealing with your self-confidence, and the excitement of getting praised for something you worked hard on and are proud of. It was so exciting to read, and I did not want to take any breaks from it. I don't know if there will be any more chapters after 25, but I would love to see what would happen next if it is still going. The chapters are longer than usual, in my opinion, so it might be harder to read if you have less time.
It's not sexist as far as I can tell, it's the weird prudishness of most asian nations, Japan especially. I think Japan sexuality in fringe stuff is so weird because it's repressed by their every day social experience. It also probably doesn't help that Japan has fallen far too down the rabbit hole of the horrible system of capitalists and overworks it's people way too much, meaning a further repression of their sex life.
