Season 1

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.

Narumi, who often suffers from nausea, suspects she may be pregnant and sees her with a study drug, but the result is negative. At that time, at Frontier Construction, the project that Kenichiro and his colleagues were working on was suddenly canceled. This work was taken over by Global Central Construction, the fourth largest company in the industry. At that time, Yoshida, who revived and opened a new office, asks Kenichiro if he wants to move to a large company. Narumi finally got a job and called Kenichiro, but Yoshino visited Kenichiro's house. Kenichiro quickly leaves his seat and tricks him into calling him a work phone.

Narumi, who Yukie recommended to re-examine her pregnancy, went to the hospital. He encountered Kenichiro, who had been hospitalized at a human wharf, and ran away without being examined. Kenichiro is worried about Narumi's strange appearance, but he can't be worried when Yoshino is involved with Narumi. I asked Mr. Kumazawa to take care of me, but a few days later, Mr. Narumi suddenly collapsed in front of Mr. Kumazawa who reluctantly came to see me. Kenichiro is not worried when he is informed that Narumi has been transferred to the hospital. She shakes off that feeling and tries to go on a date with Yoshino, but Yoshino feels Kenichiro's conflict and goes to the hospital together. However, I was surprised to hear the test results. Narumi was 3 months pregnant.

Kenichiro, who took Narumi out of Kataoka said, "If you want to be a father, you have to be a man who loves you and your children!" He was outraged for doing nothing. The next day, Yoshino calls Narumi, stabs a nail, and restores Kenichiro, but Narumi, who should have been married to a rich man, is having trouble giving birth for some reason. At that moment, Kenichiro called and was worried that he had something to talk about. Kenichiro, who met Yoshino that night, confessed that he liked Narumi. Kumazawa who appears there gets angry and hits Kenichiro. Kenichiro, who returned home late at night, told Mina, "I thought I couldn't afford to hurt people, but I was the one who hurt the most." Narumi, whom Kenichiro told had suddenly visited the apartment the next morning, "I apologized to Yoshino last night," went to "Anya" where Yoshino was working after seeing everything. To Narumi, who tries to apologize, Yoshino says, "I wonder if it will work. You and Ken are too different."

Kenichiro searches for Narumi who disappeared. Every day, I come to a place where Narumi is likely to appear in the center of the city, but I can't find the whereabouts at all. At that time, Kenichiro's mother, Masami, was admitted to a Tokyo hospital for examination. Kenichiro confesses to Masami that he has a favorite woman and wants to introduce her to her. Yoshino sees Narumi in the city. From Kumazawa's story, she learned that Kenichiro was looking for Narumi and, after worrying, informed Kenichiro. The next day, Kenichiro follows the information he heard from Yoshino and finally reaches an izakaya. What Kenichiro saw there was Narumi, who took his job seriously, as a different person. Narumi, who knows Masami, is relieved to receive a warm welcome, but she cannot say that she is pregnant. From that night on, Narumi decided to start living in Kenichiro's company house. Mina is confused by Narumi who will live with her, and Yamazaki is worried about the end of her life.

Kenichiro jumped out of the venue shortly before the performance when he was informed that Narumi had been taken to the hospital, but the performance was successful thanks to Kumazawa's rush to take the place. In the next final presentation, Kenichiro will be a unique match against Global Central Construction and Kenichiro is definitely excited to win. At that point, the president is informed that he is trying to bribe a former member of parliament to win the final presentation. Kenichiro, who is not convinced by the dirty road, protests the president. When the president fires Kenichiro, he orders a former member of parliament to bring money. Kenichiro resists, but Yamazaki is stabbed by Yamazaki and is worried that he may need to take over in order to recover from the mistakes he made in the presentation. And finally, the day of the promise to give money to a former member of parliament. Kenichiro makes a decision and heads for Cheong Wa Dae.
