Kenta left his parents' house and spent three years of school life in a dormitory. That life will soon end. On his way home from the graduation ceremony, a beautiful woman appeared in front of Kenta as he and his friends were walking on the school road while talking about their memories. Her father's remarriage partner and her mother-in-law Nanako. Nanako, who came secretly to celebrate her Kenta, is the woman she admires more than her mother. She decided to celebrate with Nanako alone, but she was so happy that she drank too much of her liquor that she got drunk and sent her to the hotel where she was staying.
