Aharen-san wa Hakarenai
The story follows the "indecipherable" daily life of the short and quiet Reina Aharen and Raidou who sits next to her in class. Aharen is not so good at gauging the distance between people (or personal boundaries), and Raidou initially sensed some distance between the two of them. Then one day, when Raidou picked up the eraser that Aharen had dropped, the distance between them suddenly became uncomfortably close.
From "way too distant" to "way too close" ... Aharen is simply unpredictable.
