I am just confused after reading this manga. I started reading this manga with bad expectations. I expected it to be a boring manga with some psychopath girl and a virgin dude on an island.
The story initially took off to an better start than I had anticipated, it felt a bit realistic and a bit unrealistic at the same time, which I understood since it was trying to be a seinen tragic comedy. After reading just 9 chapters I can say that it is currently neither a comedy nor serious. The jokes in the manga try too hard to capture the "tragic life you have if you are a virgin in Japan".

This manga just makes me sad for Japanese men, are they really incels to this degree?

The art is pretty average not really pleasing neither is it something out of a child's art book. The characters are really stupid,"I am going to die if I do not have sex but I want to have sex with an amateur."

Currently it just feels like the story is progressing to become something about prison kind of place where the mc meets a crazy girl and the story becomes crap.

My final verdict is if you want comedy or tragedy this story gives none of them. There are plenty of better manga to read rather than this dumpster fire.
