This isn't a manga or a story. The author didn't want it to be. He just wanted to draw the same naked woman again and again. Why this isn't a story: There is no dialogue or narration There is one character This one character faces zero problems Everything you ever know about this character is known by the first chapter Each chapter is 6 pages long She is naked on every page It's just drawings of a naked womanThe appeal is with watching a woman so comfortable that she's naked all the time for no reason and doesn't acknowledge it.
And if that was like a fetish, then this would be solely a story for people with that fetish.
I wouldn't even mind to see a woman like that on tv, or twitter, but on twitter it's delivered in 5 seconds, and a tv show or narrative puts the characters in different environments and has them operate in it.
The art isn't even good. It's not bad, but that's why it's a 4 and not 1.
