Maybe my mind is too tired to function, but after finishing reading this manga i got some Harada vibes from... the whole thing. Idk maybe is because Mari is obsessed with dicks just like the characters in happy shitty life, and the humor in general and artstyle feels familiar (in a good way). Not even trying to imply the author might have been inspired or whatever, just think the similarities are funny.
Don't know why the rating is so low already, the story is pretty decent as of now
