I left my parents' house and spent three years in the dormitory. - That life is about to end. - On the way home from the graduation ceremony, I was walking along the school road with my friends while talking about my memories, and a beautiful woman appeared in front of Kenta. - Her father's remarriage partner and her mother-in-law Nanako. - Nanako, who secretly came to celebrate her sword, is a woman she admires rather than her mother. - She had to celebrate with Nanako alone, but she was so happy that she drunk too much and sent Nanako to her hotel.
