I used to run a café in Tokyo, but due to tough economic times, life became difficult, so I decided to return to my distant hometown. When I visited my sister's house after a long time, Tatsuya, who had always taken care of our family, gently comforted me and lifted my spirits. I was deeply moved by his kindness and how well he'd grown up. However, I realized he still lacked experience with women, so I decided to give him some special personal guidance.
