Men - they're the root of Takanashi Chiwa's problems, which is why she never had the time nor the opportunity to have a boyfriend in her entire life. A full-time office lady and a part-time hostess, she works night and day to pay off her dad's debt from his failed business. One night at her part-time job, a high-class customer has her fired. Then the next day, she's called in to see the president - whom she had never even seen before in the office - only to find out she's to marry him! But what kind of guy is Mamiya Hokuto anyway? Will he become one of Chiwa's problems, or will he save her from them? And will this marriage even last?!
