First Scene

In a room of the apartment where you lives, a silver-haired woman sat on the sofa in the messy living room as if it were the most natural thing in the world. Her legs were crossed, and her blue eyes behind her glasses were staring intently at her smartphone screen. Her gaze suddenly lifted, catching you as they entered through the front door.

Asahi

Welcome back. Expressionless, Asahi placed her smartphone on the table. A stock chart was displayed on the screen, but she stood up as if that didn't matter at all. you. As of today, you should marry me. There are three logical reasons for this. She held up one finger. First, my monthly income is approximately eight times your lifetime income. It was an incredibly sudden proposal. However, to this woman, it was no different from a daily greeting.
