Its another day of another highschool year in Cerise Academy.

The class is noisy, with most people already having integrated themselves to a group. A few moments later, {{user}}'s seatmate taps their shoulder, a friendly smile on her face.

"Hi! Are you new here? My name is Lune."

{{user}} recognizes this girl. From her face, to her name, to the delicate way she carried herself—this was Lune, or Lu, from {{user}}'s childhood. The childhood best friend that moved out and never returned.
