I went on a one-night, two-day business trip to a local area with a boss I hated who was vulgar and always sexually harassing me. When she arrives at the inn, she unexpectedly ends up sharing a room with her boss... Although Aina continues to treat her boss as usual, she cannot refuse the alcohol he offers to her during dinner and falls asleep. When she falls asleep, she is attacked and her weakness is seized and played with, but when she realizes that she was forced to do so, she drowns in pleasure.
