Nami Kuroki, an office lady who can work well, is beautiful and has an outstanding style. She is also very popular at work, but for some reason, her favorite male employee becomes a shell and quits. One day, Kuroki and Okada, a junior, share a room with a broken air conditioner that was left behind by making a mistake in booking a hotel on a business trip. Okada, who recently got married, was worried about sharing a room with Kuroki, but he was forcibly pushed away and ended up staying overnight.
