OVA
Description
Mayu Morita is a high school student known for her frequent silence, stemming from a tendency to overthink responses. This overanalysis often causes her to miss opportunities to speak in conversations, despite her willingness to engage. She frequently conveys her thoughts and feelings through facial expressions rather than words.

Her mother taught her etiquette rules, like waiting for others to finish speaking and articulating thoughts clearly. However, these lessons often occurred during confrontations about her father's behavior, such as flirting with other women. This background contributes to classmates misinterpreting Mayu's silence as aloofness or shyness, rather than a result of her overanalytical nature.

At school, she interacts with a group of friends. The talkative Miki Murakoshi is her closest companion and one of the few people who can interpret her non-verbal cues effectively. Classmate Hana Matsuzaka finds Mayu's intense, direct gaze unsettling, describing it as "soulless," which complicates their initial interactions. Hana's self-consciousness about her curly blonde hair sometimes leads to Mayu's fingers getting tangled in it.

Mayu's silence and concentrated demeanor occasionally lead to misunderstandings. For instance, peer Ritsuki Yamamoto feels intimidated, misinterpreting Mayu's focused attention as judgment or pressure. Another classmate, the "Girl with Glasses," shows recurring interest in Mayu, often attempting to surprise her with limited success.

Her family dynamics include witnessing her mother's stern reactions to her father's social behavior, which informed some of Mayu's communication strategies. Her cousin, Yukino Morita, interacts with her in a manner described as somewhat shameless.

Her central traits – prolonged silence due to overthinking, reliance on non-verbal communication, and misinterpretation by others – remain consistent throughout documented appearances in media. Interactions with friends and family consistently highlight humorous or awkward situations arising from these traits.
