I had a little bizzare experience, I knew that something like that exist. At moment I believed that they were tied with opm and mobpsych, which weren't in my style so I never watched them. It changed when one of my fav authors posted a ff about it and I gave it a try. After searching through tumblr I saw someone saying that these series gave them khr nostalgia - and since moi was a huge nerd I went to read the manga. Welp at first I wasnt so much interested but the characters grew up on me. What about you guys?
