The protagonist Saionji Kazuki (Matsumoto Wakana) is a 38-year-old single woman who works at the app production company ress Q.The app I made has reached 5 million downloads, and my work is going smoothly!Recently, she bought a big house and started living with her pet dog. She realized her dream of %zero housework and lived a very fulfilling life both in public and private life.

However, the peaceful life changed when Toshi Nao Kusumi (Matsumura Hokuto), an engineer who returned from the United States, switched jobs to the company.Nanjian had a cold attitude, was expressionless, and had no coordination. He could only talk sense. He criticized the app made by Saionji. Saionji felt that he couldn't get along with him at all, and even wanted to get angry with him several times.

Under such circumstances, Saionji was instructed by the president Amano Ryuuji (Fujii Takashi) to live in harmony with Kusumi, so he had no choice but to go to dinner with Kusumi.

But there, Saionji learned that Kusuomi had an unexpected secret.That is, Kusumi is a single father raising his 4-year-old daughter Ruka (Kurata Eima) by himself?

Miss Saionji (Matsumoto Wakana) slapped her forehead and decided to let Kusumi and his daughter live in another apartment in her home.

Kusuomi (Matsumura Hokuto) was also overwhelmed by Saionji's momentum and said “yes”.

However, it is abnormal to be so kind to someone who is not a family member! So, he began to care about Miss Saionji unusually.

Ms. Saionji felt uncomfortable with Kusuomi's overly stubborn attitude...

Under such circumstances, Kusuomi held her daughter Ruge (Kurata Eima) in her arms late at night and went to nowhere.After Miss Saionji saw it, she secretly followed behind.There I witnessed Kusu's embarrassment as he struggled to do housework and raise children.

Miss Saionji slapped her forehead again and made a decision...!?

Because he wants to form a relationship without worrying about each other, Saionji (Matsumoto Wakana) proposes to form a “pseudo family”.Saionji was very excited about this proposal, but Kusuomi (Matsumura Hokuto) was a little confused and couldn't quite understand what Saionji meant by "pseudo family".However, Saionji decided to give it a try first to verify it!

At work, Saionji finally met Yokoi (Kenjiro Tsuda)!Unexpectedly, Yokoi has another identity!?

On the other hand, Kusumi received a contact from Hatano Satomi (Kaoru Okuki), the mother of his late wife Rui (Matsui Airi).Because I have to go to Rui's hometown to participate in the first anniversary of his death, but there is a deep gap between mother-in-law Satomi and Kusumi...

What amazing move will Saionji make after learning about the complicated relationship between these two people!?

Saionji (Matsumoto Wakana) is moved by Kusumi's (Matsumura Hokuto) unexpected smile, and their relationship falls into chaos!Regarding the state of Saionji, Youqiu (Noro Kayo) and Yosuke (Takashi Tsukamoto) asserted: "That is already love."“

Finally started the ”pseudo family“ life.However, if love and family affection are entangled, ”pseudo-family“ cannot be established! Considering this, Saionji decided to do its best to expel the budding love.However, the more he tries to expel him, the more he notices Kusumi and his behavior becomes suspicious...

During this period, Ruge (Eima Kurata) caused trouble in the kindergarten.The cause of the trouble lies in the ”pseudo family% Xiyuanji. In order to let Liuge's friends and parents understand their relationship, Xiyuanji planned Liuge's birthday party.Saionji went all out to prepare dishes and cakes that he was not good at...?

Saionji (Wakana Matsumoto) was warned by Ruka (Eima Kurata): “Don't fall in love with dad”, and realized that his faint love for Kusumi (Hokuto Matsumura) made the young Ruka feel uneasy, so he fell intoFrustrated.

Faced with such Saionji, Yosuke (Takashi Tsukamoto) came up with a clever idea, which is to find a replacement boyfriend“!If Xiyuanji finds a lover outside, maybe Liuxia will feel at ease.Xiyuanji thinks it makes sense!” and take action immediately and register on the dating app immediately.However, after dating several outstanding men, Saionji always inadvertently thought of Kusuomi and Ruka at some moment, absent-mindedly.

At the same time, the ResQ team went to Yokoi (Kenjiro Tsuda)’s home to shoot a collaboration video.The filming was going on smoothly, and by chance, everyone knew that Saionji was recruiting boyfriends on a dating app...!

Kusuomi seemed quite confused when he learned that Saionji Temple was recruiting boyfriends.And Yokoi seems to be thinking about something too...?

Saionji (Wakana Matsumoto) was confessed by Yokoi (Kenjiro Tsuda) in ambiguous words, and then Kusuomi (Hokuto Matsumura) joined in and said “Me too!”, as if caught in the Shura field of triangular relationship, Xiyuan Temple is already in chaos.

After coming back to his senses, Nan Jian felt incredible about his impulsive behavior.Then, on the way home from school with her daughter Ruka (Eima Kurata), Kusumi accidentally realized the reason for his behavior.

On the other hand, Yokoi officially begins his pursuit offensive against Saionji!Invite Saionji on a date.Although Saionji was confused, he decided to spend the holiday with Yokoi.There, Saionji felt Yokoi's immense tenderness——.

The thoughts of Saionji who wants to sort out the chaotic situation, Kusumi who wants to clearly convey the reasons for his actions to others, and Yokoi who expresses his feelings to Saionji frankly lead this makeshift family in an unexpected direction.!

Due to the suggestion of Yokoi (Kenjiro Tsuda), the relationship between Saionji (Wakana Matsumoto) and Yokoi's “temporary boyfriend” formed!Yokoi actively participates in the life of the simulated family, and even Ruka (Eima Kurata) seems to have a good impression of Yokoi.

The simulated family has been upgraded to a new form!Saionji is very excited. On the other hand, Kusuomi (Matsumura Hokuto) cannot understand the relationship between “Sim Family + Temporary Boyfriend” and falls into chaos alone.At this moment, Saionji suddenly went on a business trip to New York.Kusumi, who was left behind, took over the job, but encountered trouble at work...!

On the other hand, when Saionji encountered difficulties on a business trip, he received help from the mysterious woman Alisa (Ota Rina)...?

When Saionji (Matsumoto Wakana) went to New York on a business trip, he met Elisa (Ota Rina). Now Elisa has returned to Japan and joined ResQ as a secret weapon in the corporate strategy.

Relying on Elisa's ability, the company's development has also entered a new stage. The relationship between Saionji and Yokoi (Kenjiro Tsuda) is also going smoothly. Saionji feels very fulfilled both at work and personally!

On the other hand, Kusumi (Matsumura Hokuto) realizes that he has feelings for Saionji, so his behavior is a bit strange.In order to calm his chaotic heart, Kusumi picked up a notebook filled with memories of his late wife Rui (Matsui Airi).

At the same time, Elisa suddenly approaches Kusumi!She tried to go on a date with Nanjian alone and expressed her affection for Nanjian.This scene was seen by Saionji, who felt an unprecedented upset...?

Saionji (Wakana Matsumoto) finally realizes that he has special feelings for Kusuomi (Hokuto Matsumura).She felt that she could not continue to date Yokoi (Kenjiro Tsuda) like this, so she decided to break up.

However, Yokoi said "I can't give up so easily" and declared that he would work hard to help Saionji eliminate his feelings for Kusumi.In addition, he also proposed that as the last activity of app's cooperation with Yokoi, all members go camping together for the night.

Yokoi directly expressed his feelings for Saionji in words and actions.On the other hand, after Kusuomi heard the rumors that Saionji and Yokoi might get married, his mood became confused and his behavior became unpredictable, making Saionji very angry.

As the emotional entanglement between the three became more complicated, an unexpected event happened...

Saionji (Matsumoto Wakana) told Kusuomi (Matsumura Hokuto): “I hope you can move out of this home.”The reason is to take care of his elderly father Kohei (Asano Kazuyuki), and hopes that Kusumi will make room.

Nan Jian agrees to move out.However, the only thing he worries about is the feelings of Ruka (Eima Kurata).Ruuka, who likes “pseudo families”, will definitely feel lonely... However, Saionji is very optimistic!Even if they live apart, the “pseudo-family” will continue.

Ruka was also satisfied with this statement. The Kusumi family started their moving plan with smiles and excitement for a new life & form of “pseudo-family”!However, in this exciting atmosphere, there is a hint of loneliness that cannot be concealed...?

Luka (Kurata Eima) suddenly disappeared after leaving a “goodbye” note.

Saionji (Matsumoto Wakana) and Kusuomi (Matsumura Hokuto) feel guilty because they have feelings for each other and hurt Luke.

Desperately continuing their search for Luke, Luke's goal is an unexpected place...? And then, Mr. Saionji and Kusuomi meet an unexpected person there.

Although their hearts are connected, for the most important existence, Luka, Saionji and Kusumi have been thinking about what the “pseudo family” should do and what is the correct answer.

After discussions, missing each other, and finally forming a “family”, Mr. Saionji and the others came up with the answer -.
