I read all the other manga by the creator. They are just bad at making interesting characters. And really loves young, innocent, weak characters with guys that take advantage of them. Or a huge power imbalance ~~~~ if i had to psychoanalysis, i would say the creator was groomed as a younger person. In japan right now they have a huge problem with teens being homeless and prostituting themselves. And with that people are making it seem awesome to be homeless and go through prostitution. You can kinda see it with the manga by them called Ai no Ondo wo Oshiete yo, which is one of their better mangas

When when i tried ignore the age gap, the guy talking about him being a kid all the time, was so off putting. Or just him not wanting to have sex with the escort because he wasn't kid-like enough, was so gross. Then everything was forced. The story was boring and predictable and the characters were a yawn fest. I think it may be the author, she sucks as a character writer.
