From Taciturnity Scans:

Second-year middle school student Ayumu Kurihara changes classes and is seated next to the beautiful but strange Misuzu Tsukishima who dislikes boys. Misuzu can't get close to other people, but after being moved by Ayumu's sweet, honest personality she begins to open up to her little by little. Ayumu too is captivated by the awkwardly delicate Misuzu and the two of them become close.

V.3 (a.k.a. Second Season)

It's Shimizu Kanako's first day at an all-girls high school, and she's a little overwhelmed. Hoping to make new friends, she bumps into the odd and distant Kamei Ao, as well as her first three new friends: Aki, Rikako and Haruna. Of course, not all can be so sweet in the world of girls.
