Plot
Ota frequently makes fun of his classmate, Kashiwada, because her expression never changes. However, his prank never succeeds, mainly due to her getting clued in by his own extremely expressive face. Unbeknownst to them, Kashiwada does change expression, but can be hardly noticed, including her crush towards Ota.
