I lost my job due to the recession and came to Tokyo to look for a job, so I decided to stay at the house of my junior student, Shiroishi, until I got a job. However, it is difficult to find a job because the economy is bad in Tokyo as well. One night, I happened to witness the activities of the Shiraishi couple. Marina, the bride, was a nasty figure that could not be imagined from her calm appearance in the daytime. The next day, Marina, who knew what I was looking into, approached me with her bewitching smile.
