Kana Shinoda has been elected to be the new chief of the sales department at the mere age of 30. But on her first day, she catches sight of her subordinate Atsuhiro Saburi (who's also married, by the way) flirting with Shihomi Sashihara, a woman from the design department. Unable to sit back and watch, Kana warns him about his misconduct. However, she soon realizes that everyone else at the company simply stands idly by, ignoring the issue. Her superior even tells her to learn how to better deal with her subordinates. Apparently, this affair has been going on for five years, and everyone at the office just turns a blind eye. When Rei, a temp worker, catches Kana crying into her desk late one night handling work Atsuhiro had pushed onto her, she comes to her aid. But with the fire having spread this far, how will Rei handle these cheaters...?
