Finally, they were supposed to become a real family. Marina Nishio remarried with her husband who was much older than her, and she had been able to build a friendly relationship with her stepson, Ryota. She was happy that they had become a good parent-child relationship like a sister and brother, but suddenly Ryota confessed to her that he loved her not as a mother but as a woman. Marina Nishio was confused by the sudden confession, but she began to think of Ryota not as a stepson but as a man.
