Mother Mako learns that her son Naoya is being bullied by his friend Kenji, so she confronts Kenji sternly. However, Kenji retaliates by threatening her: "If you don't become my sex partner, I'll keep bullying your son." Though Mako resists internally, she prioritizes Naoya's safety and has no choice but to comply with Kenji's demand. Naoya secretly witnesses the entire scene. Lacking the courage to protect his mother, he can only watch helplessly, left stunned and powerless in the face of the humiliation unfolding before him.
