Morita-san wa Mukuchi OVA

Morita-san wa Mukuchi OVA revolves around high school student Morita Mayu, a quiet and introspective girl. Her tendency to stare directly at people can lead to misunderstandings, but it's not due to a lack of interest in conversation. Instead, Mayu is cautious about speaking, often deliberating so long that the opportunity to speak passes her by. Despite this, she manages a normal and happy school life with her classmates.
