Raido spent middle-school isolated due to his unintentionally unfriendly appearance, and hopes that high school will be different. He decides the first step to being more social will be to get to know Aharen Reina, the girl who sits next to him. She seems distant at first, then a little too close, and before long Raido comes to understand that Aharen has more than a little trouble at gauging the distance between herself and others--in more ways than one.

Aharen finds herself having even more trouble with distance than usual thanks to her vision being impaired. When Raido tries to help her with eye drops, he incurs the wrath of Aharen's imposing childhood friend.

The periodic shift of the seating chart is approaching, threatening to put Aharen and Raido's friendship to the test.
