I had a coffee shop in Tokyo, but due to the recession, I decided to return to the countryside... When I visited my sister's house for the first time in a while, Tatsuya, who I used to look after as a child, cheered me up when I was feeling down. Tatsuya has grown up to be a Kokoro and fine young man, but he doesn't seem to have grown up much when it comes to women, so I'm giving him special private lessons...
