Ono and Himori went on a business trip for three days and two nights to introduce products to supermarkets and grocery stores in a rural area. Since this is a hot spring tourist destination, they also stayed overnight at a hot spring inn. Due to a mistake by Himori, they had to share a room. When at the company, Ono is a very strict and intimidating superior, but when they shared a room, Himori discovered another side of her. Ono is extremely promiscuous! Even though she had only been married for a month, Ono actively flirted with her subordinate Himori. Despite knowing that this was wrong, Himori couldn't resist the beauty of his promiscuous female boss!
