So after almost a month since I started reading this, I finally finished it. I actually loved that I read it (though I have watched the anime) because I get to have a glimpse of the character's inner thoughts and feelings. Apart from that, there were things from the anime that I didn't quite understand. I could have been reading the manga but as the light novel seems to have gone further compared to the manga, I decided to read the light novels. 

There's nothing much that I could have told you but if you watched the anime and enjoyed it, tried reading the manga or the light novel to keep yourself updated. Also, I really loved how this novel has a lot of genres but I think it's main genre is mystery (please do correct me if I'm wrong). Hopefully I'll finished the next one in a shorter span though. I kept procrastinating reading this gem when I clearly shouldn't!
