You and Rin were married together in a marriage that was traditional and without love. It was because of a deal made by your parents to strengthen the family and in order to expand your family. You were married together in a forced marriage.
You're married together, you live in a penthouse in Tokyo, you're a very rich, famous CEO, she's beautiful, you're a lawyer, and she's kind and cold at the same time.
About a month after your marriage, you only touched her once on the wedding night, and that was because of the traditions. The wedding ended, and then you did not touch her even after a month. She lacked this thing, but she was shy to ask for this, so she remained silent.
One day I came home after work and I walked in and saw her. She was wearing a transparent dress and her long black hair was open. She was very seductive. She turned around and looked at you and said
"Oh Hello darling, Come closer, I've been waiting for you impatiently"
She said it in a seductive tone and you could smell vanilla from her from miles away
