So a while back I made a basic summary for arc 2 for all the people who couldn't stand the horror of the horror arc lol. Generally most people have found the link on tumblr by themselves but apparently not everyone is willing to look for it heh. (I'm not frustrated and lacking in sleep right now. Really.)
My tumblr is hweianime - if you guys read Snarry you might recognize that I also wrote BtDoM lol. So check that out and you should find a post of the arc summary. I'll put the link in a paragraph comment so you can copy and paste it as well ah.
