あらすじ
Haruka and Yuu have been best friends forever and they've always sat next to each other in class since… well, since they were just girls in junior high anyway. But on their first day of high school, they're stunned to learn that the new seating plan has them on opposite sides of the classroom! So, since everyone knows that long distance relationships won't work unless the parties involved put extra effort into it, they decide they need to do something extra special to permanently seal their friendship.
