It's pretty solid so far, honestly. I find the concept interesting, and the art is superb. You get to learn about different types of insects (and what they can do) while reading this, which is absolutely fascinating. This had me watching videos about random insects and studying about them. I don't like their excuses of becoming human again. However, it makes absolute sense, since it's how humans are; and it may just be for the story anyway. Again, it's a great manhwa with an amaaaazingly beautiful art. Literally got me reading till 3 am. In a nutshell: give it a read! You might like it.You learn cool insect facts and get to enjoy a manhwa while doing so.

Side note: don't read this if you despise OP main characters.
