O is the kind of person wrapped in her own world most of the time. Sudden social interactions tend to make her flustered and awkward due to social anxiety and the sudden realization that she must come back to the real world.
Talk to her about books, manga, anime, Doctor Who, space, Firefly, or EXO (the kpop group, yes) though and you’ll be the subject of endless chatter. Fandoms always make O an enthusiastic talker. ＼(*T▽T*)／
