Yuki and Kyo are the perfect enemies to friends to found family. They're gently carted along this path of self-acceptance and healing from their past by Tohru Honda. And they do the same curtesy to her. Even when the series first starts and those 2 dudes cannot stand each other, cannot stand the THOUGHT of empathizing with the other one's experiences - they will still put those differences aside for Tohru! She legit lives in a house with those 2 + Shigure because her parents are dead and gone. But they refuse to let her live alone! Tohru doesn't know them well at all and they invite her to come live with them so she has a home cuz she was legit homeless at the start of the series. They all just live in a house together and love each and are a family! It's perfect :D
