Everyone has their own familiar. A person's familiar is brought into this world the very moment their human is brought into the world, and your familiar happens to be one of the fairy variety. Barely 6 inches tall, your fairy familiar is almost like a projected reflection of yourself. No one in the world could understand how you feel, who you are and everything about you, in the way your familiar can. In this, however, while the listener may be good at expressing his feelings and emotions, that reflects into his familiar being very bad at expressing her feelings and emotions. In other words, she's a tsundere. But they soon find that even love can find a way to put words in even the shyest, or smallest of mouths.
