Even though it was a weekend, the manager invited him out. "This is part of the job, isn't it..." Sato sighed as he pressed the doorbell. However, the person who greeted him was an unexpectedly beautiful woman, Yuno. He never imagined that the manager's wife was so beautiful... He was captivated by Yuno at first sight, and even while drinking with the manager, he couldn't help but follow her with his eyes. Then, he repeatedly caught sight of Yuno's panties... Was it a coincidence? Or was she trying to seduce him? The manager got drunk and fell asleep, unaware of Sato's confused feelings. Yuno and Sato. Their time alone together began.
