Finally I've finished this series. This is the best yaoi book series that I've ever read in a long time. Both Uke and Seme have chemistry. The writer didn't just match A and B without any reasons. Each has their backstory and I have no doubt why they end up together. The plot of the last two books is interesting. The beasts vs human. I was more than okay with that anticlimatic ending as this is the style of this author's narrative since the first book.
This series surely set my standard so high for those yaoi books that I'm going to read.
