On the verge of his exams, Satoshi moves into his aunt's house to receive care and support from the family. His aunt, as beautiful as ever, treats him with warm and friendly affection, causing Satoshi to gradually fall for her. Noticing his growing attachment, she scolds him sternly—but accidentally lets it slip that he's still a virgin, reacting with a look of surprise. Laughing, she teases, "Huh? No way! Still a virgin? That's so sad... Should I be the one to graduate you then? (laughs)?" Her words leave Satoshi even more flustered, and in that moment, he sees clearly for the first time the full intricate tattoos covering her body. Struck by their beauty and intensity, his admiration deepens as he is drawn into the world of adult desire.
