I have yet to fully decide how I feel about this, but since there are no other reviews, I thought I'd offer my thoughts. So far their hasn't been much interaction between the 4 main human characters and really no story of any kind, though I get the impression this may pick up? (thus why I'm undecided) But if not, it pretty much just alternates with a different character per chapter.
It really just centers around the animals and also has a lot of educational info thrown in there. If it weren't for the bad language, I feel like it would be something to give a child who wants a pet. haha Some of the characters are also kind of annoying (well, mostly just the obnoxious twin doctors)
That's not to say it has no redeeming qualities. I've definitely gotten a few laughs and I think the idea of a school with pets sounds fun. I totally love the guy with the hamster named poop and will continue to read it for chapters with his character if nothing else.
But I have to say, out of the 3 manhwa by this author/artist group, this would be my least favorite. I was drawn to their other works by the gorgeous artwork, which is lacking in this. That's not to say the art is bad, it's just much more simple than 19/21. If I hadn't fallen completely in love with their other manhwa I don't know that I would have read this one.
