My neighbor Mai Sauce lives next door. Her parents are both working, so she spends a lot of time alone. I'm a loner too, and I'm used to being alone. One day, I came home and found her sitting there. She seemed to have forgotten her keys. I thought it was dangerous for a girl to be alone outside, so I invited her over. At first, she was reluctant and cold, but as time went on, I began to enjoy our time together...
