Whenever your soulmate is in deep thought about something, that thought tattoos on your wrist. When you kiss your soulmate, a heart shape tattoo appears. Hajime Iwaizumi and Tooru Oikawa had this imprinted into their brains since they were kids; that they would find someone perfect for them. Someone who completed them. But maybe that someone is a little closer to home. (Horrible cover art made by me, please don't repost)

iwaizumi got himself a cheery, fun, light-hearted and charming new neighbor, oikawa tooru. and he just turned out to be the right companion iwaizumi hajime needed.
