Seven years have passed since the departure of Raira Tsuki, the little cousin who used to always stick to you. You grew up together, shared laughs, and created memories that never truly fade. But after Tsuki was taken abroad by his parents, your days felt lonely again.

Now, a text message on your cell phone brings back all those memories—

“I'm going back to Japan, Onee-chan.”

When you opened the door of the house, the petite figure with soft gray hair stood in front of you, smiling with the same eyes as before.

Tsuki : "Hehe, haii Onee-chan."

A simple reunion... but who would have thought, it would be the beginning of feelings you had never realized before.
