After passing the entrance exam for university, Akira immediately left his family and moved into the school's dormitory. During this time, his father also remarried to another woman. He did not harbor any hate for his stepmother; in fact, he was very grateful for her constant care and concern, which helped him forget the feeling of loneliness from living alone. Finally, the graduation day arrived, but due to work commitments, Akira's father could not attend. Just when he thought he would have to experience this significant day alone, he suddenly saw his stepmother waving at him from a distance with a happy smile. They went out to celebrate together, and since his stepmother drank a lot, Akira had to take her back to the hotel. Just as he was about to leave, she held him back, gave him a passionate kiss, and expressed her feelings for him. And thus, the inappropriate relationship between the two began from that moment.
