After my wife left, I was left with only the mortgage. Before I knew it, I was drowning in alcohol, wandering the city streets alone every night. That's when I met Tsubaki, the most amazing woman. I didn't know much about her background, but I fell head over heels for her. One day, a young man came to the shop. Tsubaki's face paled when she saw him. Upon closer inspection, I noticed a large birthmark on her arm. A bad feeling washed over me. And then, the worst possible thing happened.
