Want to know what I like? Then keep on reading.
I like to watch anime, play video games (especially RPGs), read / write fanfictions, read anime mangas, art, sawing, and cosplaying.
As a Reader:
I only read stories mostly about anime and video games, though I have taken a liking to read about other stuff like certain movies and series.
The aspects I love the most in stories are lots of angst, dark / matured themes, and serious story line (though I might read a few comedies, as well as other themes). To put it simple, I mostly like stories where my favorite characters suffer because they have mental angst (over the past or present situations), are tortured, injured, ill, try to commit suicide (succeed or not), or are killed (either by someone or slowly because of something). I like to read a few out of characters situations and alternative universe stories (though both depend heavily on the story line), as well the same universe (example: like Suikoden IV / Suikoden V).
My favorite pairs are usually the main characters when they are implied as such (examples: Ritsuka x Soubi from Loveless, Chrno x Rosette from Chrno Crusade, or Tidus x Yuna from Final Fantasy 10). I don't care if it's a boy / boy couple because I love yaoi / shounen-ai. Is very rare for me to like a pair that is not implied in the main story line. There are however some exceptions (though it depends heavily on my mood and how a story is progressing), as I have read stories with the characters I like the most as alternative pairs (example: Kamui x Subaru from X/1999 or Tir x Lazlo from Suikoden's I / IV).
About my favorites bellow:
I only add stories longer than 10 chapters. Those less than that I save in my personal records for offline reading. I only favored authors that I like all their stories (this doesn't mean I don't like you). If I review a story or sent a PM that means I like your writings. I just picky like that.
