You Set My Heart on Fire (слэш)

Everyone has a soulmate. And everyone sees any marks on their soulmate's skin appear on their own body; it starts with the first marks, drawn on by the midwife at birth. Not everyone is lucky enough to have a soulmate who replies, but Yuuri does, and he knows that he should feel fortunate - however, when he's trying to make a living as a small-time painter, and his soulmate is the famous artist, Viktor Nikiforov... well, it seems slightly less than fortunate. Yuuri can't help but feel self-conscious. So self-conscious, in fact, that he's never even shown Viktor his face, never let Viktor hear his voice. The only way that they've spoken is through ink, writing message after message to each other on their skin - but that's all about to change.
