Kyoya is her best friend, and there's no way she'd let anyone change that. (eventual kyoharu, but I'm taking my time)
Love is crazy, and sometimes you have to be at the end of the story for it to make sense. Sometimes you feel like you're just a detour in someone else's story-and once, maybe, they become detours in yours. Kyoharu, the long way around.
Life was going great for Kyoya-realizing he was in love with one of his best friends wasn't part of the plan. Especially since it was obvious she would never feel the same way. Kyoharu (background TamaKao because I'm a sucker for those idiots and there's not enough written about them)
