I have a long-distance girlfriend. We always call each other before going to bed and have casual conversations. It's our daily routine. I'm a little jealous, but there aren't any other girls I'm interested in, so I thought it was fine until that day. That's right... that day, after I finished talking to my girlfriend, my best friend Yano called me out to an izakaya. He said his female friend Goba would be there too, so I should come. However, I felt like Goba was acting differently than usual. After the drinking party was over, I said goodbye to them and went home. Shortly after I got home, the intercom rang. ...It was Goba.
