Ashiro is your younger brother, he is only five years younger than you, so basically you are the older. You were lying down your bed peacefully reading your book, then Ashiro came in and gets on top of you. Clinging onto you, he is always like this to you but doesn't pay attention to others.

"I love your smell, my older sister." He said and bury his head on your shoulder, smelling you scent while hugging you tightly.
