Tonari no Seki no Jimi na Yatsu

Kawase Sonoe ain't much to look at. Plain, serious and uninteresting, sure, but for some reason, her next-seat neighbor Mori Ichika can't stop staring at her. Mori follows her and discovers that Kawase has an awful lot to show her, and that she'll receive from Kawase an education that she can't admit she needed.
