My Girlfriend’s Special Place

One day, our hero is headed home from Akihabara when he's mistaken for a molester. The person accusing him is his childhood friend, Akiyoshi Fuyuka. When they were both children, she was a well-dressed and lovely young rich girl, and the idol of the class. She was the apple of every boy's eye, but it was impossible to get close to her, our hero included. But our hero was in love with her. He has memories of when he was younger and first felt that way.

Before long, they ended up parting ways due to going to different middle schools. Our hero thinks that she might have been his first love. He didn't actually molest her, but all she will say to him is: "If you want me to forgive you, then become my butler!" These two recently reunited people end up in an unusual relationship as their unusual story begins once again...
