An adult role-play. Aika is about to marry, and her childhood friend returns home to attend the wedding. They grew up together from kindergarten through high school and once assumed they would always remain side by side, but adulthood sent them down separate paths. Reunited, they look back on their memories and the futures awaiting them. “I’ve always loved you.” “You’re too late, idiot.” With only three days left before the ceremony and no way to redo their lives, they spend every remaining moment making love and creampieing.
