I have a long distance girlfriend. We always call each other before going to bed and have a casual conversation. That's my daily routine. I was a little jealous, but there were no other girls I was interested in, and I thought that was fine until that day. That's right...that day, after I got off the phone with my girlfriend, my best friend Yano called me to a bar. I also have a female friend, Goba, so I told her to come. However, I felt that Goba's behavior was different from usual. After the drinking party was over, I said goodbye to the two of them and went home. Shortly after arriving home, the intercom rang. ...It was Goba.
