I'm Always There For You.

Two years ago, Rukia Kuchiki left the World of the Living and the boy who changed everything about her world. She never expected to come back like this.
Sent by the Soul Society on a mission she cannot refuse, Rukia returns to Karakura Town with a single order - eliminate the growing threat within Ichigo Kurosaki before his inner hollow consumes everything and everyone around him. Including herself.
But the Ichigo she finds is not the one she left behind. He doesn't remember the Soul Society. He doesn't remember being a Soul Reaper. He doesn't remember her.
And yet somehow, his heart already knows her name.
Torn between her duty and everything she feels, Rukia must ask herself the one question she has spent two years running from - how do you save someone you love from themselves?
And what happens when saving him might mean losing him forever?
