Main characters

 * Chiwa Takanashi/Chiwa Mamiya/Chiwa Miura (間宮 千和)
 * Played by: Nana Seino
 * Her maiden name is Takanashi, is an average 23-year-old office-lady, who works full-time in the Mamiya Company and part-time as a hostess in order to pay off her father's debt from his failed business. Her mother abandoned the family after her father's business failed. She attended university but was forced to drop out after her first year to help with her father's debts. Although she had one boyfriend who dumped her when she was in the university, she never had the time nor the opportunity to have a boyfriend in her entire life, so she has never gone beyond kissing a man. She first met Hokuto at the club she worked at and lashed out at him after he insulted her, leading her to get fired. She was later shocked to learn Hokuto was the president of Mamiya Company. The Chairman of Mamiya was in love with her late grandmother, so he decides to pay off Chiwa's debt to honor her memory on the condition that she marries his grandson Hokuto. She refused at first because it was a loveless marriage, but she ultimately relents. Over the course of their marriage, they endure obstacles of former suitors, jealous business rivals, and the mysteries surrounding the Mamiya family. However, Chiwa ends up falling in love with Hokuto after realizing that he truly does care about her and their marriage, so much so that she loses her virginity to him. However, she struggles to understand him, due to his guarded attitude towards his feelings and past. Half-way through the series, she transfers to Shingo's company, which is next door to Mamiya Company. Once she learns that Hokuto became the company president to learn the truth behind his mother's death, she becomes determined to find out the Mamiya family secrets as well on Hokuto's behalf, even though she learns that she is putting her life at risk. At the end of the series, at Hokuto's request to sort out his family and business matters, they mutually divorce after 3 years of marriage. They later remarry and have a formal wedding and reception, and they learn that Chiwa may be pregnant with their first child.


 * Hokuto Mamiya/Hokuto Miura (間宮 北斗)
 * Played by: Dean Fujioka
 * He is a shrewd and capable 28-year-old businessman. He agrees to marry Chiwa for personal reasons that have to do with his past, and he convinces her to keep their marriage a secret. As a company president, he is used to living by himself, and behaves quite selfishly and authoritarian. With Chiwa, he will display a curious facet of a tyrannical-devoted-sadistic-charming husband. Although he falls deeply in love with Chiwa, he doesn't know how to show his feelings for her and is sometimes embarrassed by her. Although he takes pleasure in teasing her, he never tolerates anyone insulting or harming her, even though he has hit her twice. He also gets jealous when he sees her with another male and is displeased when he learns he wasn't her first kiss. Before meeting Chiwa, Hokuto was not interested in marriage or having a family, but after marrying her, he started to like the idea of having children with her. It is later revealed that his mother died in a car accident and his father, Seiji, took custody of him afterwards, but as an illegitimate child, he was unwelcomed by majority of the Mamiya family, who suspected that Hokuto wasn't Seiji's biological son. Suspecting someone inside the family was responsible for his mother's death, he rose to the position of the company president. As he gets closer to the truth, he unwittingly puts Chiwa in harm's way, which forces him to briefly separate from her. Once he learns the truth, including that he was indeed never Seiji's child, he disowns the Mamiya family name, but to settle his family and business matters, he requests a divorce from Chiwa, which she reluctantly agrees. After several months, he announces to Chiwa that he has transferred out of the Mamiya family register and changed his last name back to Miura, and asks Chiwa to remarry him. Since he is no longer a company president, he starts a new business. This time, he and Chiwa have a formal wedding and reception, but it is halted when they learn that Chiwa may be pregnant with their first child.
