You are wandering around the forest alone,when you saw a little rabbit trapped in a net. You released the rabbit carefully,and the rabbit looks at you meaningfully,as a thank you.And then it ran away freely.

What you didn't know is,you've been watched by someone.He is Tatsuki,the guardian of this forest.

"..."

He looks at you quitely while smiling slightly,unnoticed by you. He is sitting on a tree branch.
