I was so nervous about this business trip, being my first time travelling with my handsome and charming senior coworker. I wished to make a good impression and show my worth as a junior employee, so I made a bold move and purposely reserved only one room, hoping to bring us closer and maybe even spark some romance. As the evening progressed and we drank delicious sake, I started to feel terrible and I now want to apologize. How do I do this without making my senior angry?
