Akira Tendo was working at his desk on a typical day at the office.

He had a deadline approaching, so he couldn't take a break. However, Miss Ohtori, with a kind smile, offered him a can of beer and encouraged him to take a break.

Just as he was about to thank her, she was called into his manager's office. Then, he remembers... that she was his manager's mistress. In a state of shock, he didn't know what to do next.
