1986 - Ichiro Ogawa (played by Sadao Abe) was a physical education teacher in the Showa era. He was famous for his strict guidance, which he called “the whip of love”.He also serves as an advisor to the baseball club and is known as “Hell Ogawa” by the students.

On the other hand, at home, he is a normal father, raising his 17-year-old daughter Junko (played by Yumi Kawai) alone and taking care of her daughter's bad behavior.Recently, Junko is very concerned about the time of Ichiro's return, worried that he will bring a man to her house to have sex with him.

One day, Ichiro was taking the bus home while smoking as usual, and ended up dozing off.

When Ichiro wakes up, he sees a high school girl boarding the bus wearing a skirt with her panties exposed and noodles hanging from her ears.Ichiro notices something off about his appearance and points it out, but the passengers argue, saying Ichiro is the one smoking in the car.Ichiro got out of the car as if he was running away, but what he saw was a different scenery, with people wearing strange clothes he had never seen before.

He finally found a familiar coffee shop. Before he could fully understand the situation, Ichiro became angry and drank the beer of Inujima Nagisa (played by Naka Risa) on the counter without permission, and the two had a dispute..

At the same time, on the same day in 1986, Junko was suddenly confessed by Takasaka Kiyoshi (played by Sakamoto Aito).Kiyoshi is a junior high school student who travels back from the Reiwa era to the Showa era with his sociologist mother Sakae (Yoshida Yo).He met Junko by chance on the street and fell in love at first sight.Although Junko secretly has a crush on Mutsumi Akitsu (played by Hayato Isomura), known as “Muchi-senpai”, she still tries to bring Kiyoshi into her home...!?

What was “normal” in the Showa era was “inappropriate” in the Reiwa era!?

The time lapse comedy depicting the gap between us and the self-awareness of empathy after slipping from the “Showa” era to the “Reiwa” era begins!

Ichiro (played by Abe Sadao), who returned to Reiwa, received a call on his smartphone from Sakae (played by Yoshida Haru) in Showa.Nagisa (Nakazasa) and Akitsu (Isomura Hayato) don't believe Ichiro's time-lapse story, but they can't hide their surprise when they learn via video call that Sakae is indeed in the Showa era.All that aside, Ichiro pleads with Sakae to come to his house immediately to avoid Junko (Yumi Kawai) and Kiyoshi (Aito Sakamoto) getting into trouble.

Ichiro once again explains to Nagisa and Akitsu what has happened so far, and confesses that he is curious about the reason for Nagisa's tears when they first met.There, Nagisa starts talking about the events that have happened so far, but the story seems to symbolize the difficulties of modern ways of working.

Nagisa, who lives a depressed life, faces another problem.At that time, Ichiro...!?

Ichiro (played by Sadao Abe) returns to the Showa era after accidentally slipping and returns to the house where Junko (played by Yumi Kawai) and friends are waiting, as if nothing had happened.At the same time, in Reiwa, Ichiro suddenly disappears, and Nagisa (played by Nakazasa) and Akitsu (played by Hayato Isomura) are worried about his whereabouts.

Two days after Ichiro disappeared, Nagisa and Akitsu met Sakae (played by Yo Yoshida)'s ex-husband and time machine developer Masakazu Inoue (played by Hiroki Miyake) in the cafe “SCANDAL”.While listening to Inoue talk about the secrets behind the development of the time machine, Nagisa receives a smartphone call from Ichiro, who lived in the Showa era.

Inoue then starts talking about the dangers of “Time Paradox”, which is that if the past is tampered with, the future will change.

Meanwhile, Junko said she will appear on the Showa variety show.Minors must be accompanied by a guardian, so Ichiro and Sakae will accompany them to the studio.At the same time, in Reiwa, Nagisa is involved in a huge scandal that occurred in the program run by senior producer Kurita Kazuya (played by Yamamoto Hiroshi)...!?

Ichiro (played by Sadao Abe) and Nagisa (played by Nakazasa) suddenly burst into flames at the moment they were about to kiss.They realize there is some kind of barrier between them.

Later, in the cafe “SCANDAL”, Inoue (played by Hiroki Miyake) finally reunited with his mentor Ichiro.With Inoue's help, Ichiro changed Kiyoshi's (Aito Sakamoto) smartphone to his own name, downloaded a messaging app, and took pleasure in knocking it out.I don't know if this will develop into more problems...

Nagisa (Nakarisa) brings her classmate Hamura Yuki (Uka Yuka) to Ichiro (Abe Sadao) who continues to work as a counselor at EBS TV.Hamura is preparing to create a TV series with the great screenwriter Kentaro Emen (played by Seiji Ikeda) whom he admires, but he is troubled by what happened at that meeting.Ichiro decides to attend the meeting with Emoken with Hamura...

Meanwhile, Junko (played by Yumi Kawai) is worried about Ichiro who doesn't come home often.At this time, Akitsu (played by Hayato Isomura)

After learning the fate of Ichiro and Junko, I took the reluctant Ichiro to a certain place...!?

There, when Senior Muchi learned that Junko (played by Yumi Kawai) had gone back to the Showa era as a result of going astray, he began to make a fuss, saying that there was no point in coming to the future. But when he heard "Inoue (played by Hiroshi Miyake)"tree decoration)?

Meanwhile, announcer Takeshi Kuramochi (Oseki Yuta), who has been with the company for seven years and was demoted due to a past extramarital scandal, seeks advice from Ichiro (Sadao Abe).
