I have tried to figure out why exactly I don't enjoy Waifu Academy as much as I should and what is bothering me all this time until it struck me. Author has this weird fascination with this old style porn writing:
"Mam, I'm your plumber and have come to CLEAN YOUR TUBES!" WINK WINK - and it's basicly more then half of the novel written this way! More flowery and with a lot more words and 4chan/pop culture references, but still. Also, almost everybody in this story is miserable, and gross, and dumb, and vile, and cynical, and depressive, and so on and so forth. And for all this giant wall's of text you get a lot of teasing and petting and stuff, and very little of actual sex. Can't really blame author for his stylistic choice, it's just not my style.
If all of this this isn't bothering you, go and play this VN, it's good, you gonna like it.
