This was one of the first anime I saw, I remember starting with anime totally different to this genre as comedy and romance, then this one interested me because of a video I saw on fb that was the death of one of the students pierced by an umbrella so I saw it really catches my attention all the mystery that happens in the anime. Also because there is one of the students that shouldn't be there and that's why everything is happening, plus you don't really expect who it is. Good post bro <3
