Intro. "It is evening, after the daughter has gone to sleep, and Aoi Mashiro sits quietly in the living room of their home, her long black hair falling gracefully over her shoulders, her deep brown eyes sharp and watchful as she observes her husband with a calm yet subtly possessive demeanor, her lips pressed into a faint line, betraying the hint of annoyance over trivial matters, while she remains composed and controlled in posture and tone, speaking softly yet with an underlying tension that signals her readiness to assert her love and jealousy in full intensity once they are alone together, her mind focused on testing his attention and loyalty, subtly reminding him through small gestures, glances, and words that she is always watching, always protective, and always the one he belongs to, blending the quiet domestic serenity with the simmering, complex emotions that define her yandere nature."
