The characters in this series are fucking good with their own unique traits but somehow the plot itself is so damn mediocre I have to force myself to continue reading to know if the story will get any better.
There are no flashy scene that will make me shout for more but there are honorable moments where I find pretty fucking interesting, but afterwards it just return to boring again.
The relationship going on between MC and Heroine is really interesting. At first the MC only using/manipulating the heroine for his survivability but ended up falling in deep affection/addiction towards her existence. She is the only one that would accept him as a human(vampire). MC tried to keep down the urges on drinking human blood so he can keep his humanity but the heroine is spoiling him with kindness by letting him drinking her blood.
