Series that are BOLD+UNDERLINED are main fandoms of mine. BOLD is something that I love, but not main. ITALICS means I follow it, but it's not too big. STRIKETHROUGH is either something I used to follow but I don't like it anymore, or it's something I just don't care much about anymore, but have knowledge of.
