This is one of the best sol i have ever read.
The second half of this manga is definitely the one of the best across all genre!! (its too good after ch 55+, 57-58,62,69,78-81, these are just perfection )!!
About the first half or so, cant complain much because
1. It is actually quite good, some people might get irritated but i was not one among them!!
2. It sets the tone for the later half, although i realize that many people may drop this hidden gem in the first half itself!!
