I'm bored. So I'm going to ask plus book questions.

favori leading guy?
favori leading girl?
favori animal/pet?
favori best friend?
favori friendship?
favori pairing?
favori setting?
Least favori of all of those?

I'd prefer if toi used actual livres for your answers, but I guess if toi don't read, toi can use other things (anime, manga, tv, etc). As long as the réponses aren't about real life.
