Kenichiro Matsushima works for a mid-sized construction company Frontier Construction. Until recently, an apartment was built here, but it was demolished by the remodeling of Kenichiro's company. One night, Kenichiro went to the scene to attend a party with his colleague Shiro Kumazawa. Kumazawa is worried about the drinking party with Yoshino Machida, who is waiting for the party, and feels uncomfortable. Narumi, who began to suffer from abdominal pain, was rushed to the hospital, but he ate too much. The next day, Narumi visited Kenichiro and went to his office. He seems to have found her whereabouts at the address of the invitation.

Seiichiro was sent to the scene by the Sales Development Department after being beaten by a famous interior designer who tried to prove Narumi's innocence. However, Narumi went around Kenichiro without regrets when he asked for a boring errand. One day, Kenichiro took the position of "explainer" and persuaded the local residents to oppose the condominium construction plan of Yoshiki Yamazaki, the general manager of the sales development department. Around the same time, Knieda, who had just been released from prison, appears under Narumi. Kunieda is a former boyfriend of Narumi. He was arrested for growing cannabis, rooted because of Narumi and pushed the meeting, but Narumi responded casually. There, he looked up the history of Narumi's mobile phone and found out Kenichiro's name, and thought he was a newcomer and joined the company. In addition, Narumi lied that it was Kenichirou's wisdom to tell her about her cannabis to distract Kunieda.

Kenichiro, who approached Narumi, requested that he appear as a model in an advertisement for a building that will be completed soon. Kitaro, who owns the building, found that the woman she was looking for to fit the image of her model was Narumi. Furthermore, Mr. Takaishi says that if he can persuade Narumi, he will leave the construction of the next building to Kenichiro's company. That would be a great job to make a 3 billion yen project. Kenichirou promised to attend the party at the "Anya" general store where Yoshino works, but she gave up and invited Narumi to a Chinese restaurant. Narumi, who came out to the store with Yukie, can tell Kenichiro that he can't see himself even if he looks cool. Faced with Narumi's anger while curbing his anger, Kenichiro agreed to become a model and promised to take part in the upcoming ad shoot on Sunday.

Since Kumazawa made a date, Kenichiro and Yoshino have come over to enjoy lunch together. Kumazawa is fed up with Kenichiro that he can't boil. Also, Narumi is grateful for taking on the advertising model and don't worry that she might bring trouble for Kenichiro. On the other hand, Narumi fights with Yukie and is kicked out of the apartment. Narumi calls Kenichiro and asks him to stay home. Kenichiro is lost to Narumi, who insists that she will stay even if she refuses. Yoshino, who couldn't see the situation, offered to stay at her own home. Narumi enters her mansion despite Yoshino's favor. At that moment, Kenichiro is contacted by Yukie. Yukie complained that Narumi had been sitting in the apartment for half a year, even though she said it was only a few days, and that she was suffering from the inconvenience caused by all the confusion.

Kenichiro, who accepted Yoshino's feelings, finally began to notice his love for Yoshino, and the two were in a good mood. On the other hand, Narumi, who returned to Yukie's apartment, has free time and asks Norio for a part-time job. Around the same time, a remodeling project that failed two years ago was resumed at Frontier Construction. Finally, it was decided to sell the "Yoshida Building" whose eviction problem was not resolved. Under Yamazaki's leadership, Kenichiro reconsiders his new plan. Kenichiro promises to persuade Narumi, leaving Yamazaki impressive even if he is banished by rude means. After this, he met Norio and was told that it was the son of the owner of the building who hired Narumi. Seven years after the owner of the Yoshida Building disappeared, the owner's death was confirmed and an inheritance dispute between the brothers arose.
