Yuri Tadokoro lost her husband at an early age and raised her son alone. Now that her son has grown and moved to the city for work, life had finally settled—yet she began to worry as his temperament grew increasingly unstable. Hoping to lift his spirits, Yuri planned a hot spring trip. Upon arriving at the inn, she suggested they soak in the baths. To her surprise, her son asked to join her. Hesitant but concerned for his well-being, she agreed. Surrounded by the soothing scent of the warm waters, Yuri felt her heart begin to relax. Late into the night, as she slept, she sensed movement against her body. Waking suddenly, she found her son half-undressed, touching her beneath her yukata. Shocked, she demanded, "What are you doing?" He replied, "I want you, Mom," as he continued caressing her. Yuri firmly rejected him; dejected, he hung his head and left the room. After some time, worrying over his state, she followed him. Seeing him sitting alone in sorrow, she quietly approached, closed her eyes, and whispered, "It's okay... if it brings you any relief," offering her lips to him.
