I can't think about marriage yet, so I want to break up. It was my last phone call with my girlfriend of two years. It was so sudden... I felt like I had lost everything... I couldn't think about anything. Then my senior from university, Ai, invited me out for a drink. "Men who are depressed are cute, aren't they?" she said, and kissed me. It was so sudden that I was surprised... I thought I had no sexual desire, but from that day on, I started having sex with her so much that I forgot about her.
