I've been working at a smartphone manufacturer for two years. Today I'm going on a one-day business trip to the countryside with Azuma-senpai, a senior I admire. I was excited to be alone with my beautiful senior, but Azuma-senpai has a gloomy look on her face the whole time... Then it's time for a business meeting. Unfortunately, I forgot the documents and the deal is cancelled. We have to quickly stay overnight and try again tomorrow... As misfortune continues, the nearby hotel is fully booked. We end up staying alone in the only available room we can find...
