I drank too much at a part-time drinking party and missed the last train, so I didn't have the money to go home by taxi and was thinking about staying at a manga cafe, but thanks to the kindness of my colleague Shiraki, I ended up letting me stay there. It seems that her husband is working in the business trip, and Shiraki and I walked the streets together at night, carrying ulterior motives. I have a girlfriend, but I'm only one time so I guess it's OK as long as I don't know. I had no idea that a terrifying experience awaited me so much that I regret such a sweet way of thinking...
