Brain surgeon Masaru Kawauchi suffered a brain injury in an accident and suffered severe sequelae. Not only did his memory of the past two years completely disappear, but new memories could not stay for more than one day.Therefore, Xiaoya can only do auxiliary work as a nurse, but in front of her, the weird brain surgeon Yuji Sanpin appears.Through his words and deeds that do not read the air, do whatever he wants but bring help and guidance, Xiaoya once again embarks on the path of being a doctor while being a patient.Soon, the mystery hidden in Xiaoya's missing two years of memory was revealed...

A year and a half ago, brain surgeon Masaru Kawauchi (Hana Sugisaki), who suffered brain damage in an accident, suffered from memory impairment and lost all the memories of the past two years. The new memories are only for one day.Memories of one day will fade away.Get up at 5 o'clock every morning, read the diary on the table, and re-remember the lost memories. The day starts like this.

Currently, Masaru Kawauchi is receiving treatment from Koichi Osako (Shin Iura), a professor of neurosurgery at Kanto Medical University, and is working at the training hospital where he lost his memory. However, he does not perform any medical treatment and only works as an assistant.

One day, the brain surgeon Yuji Sanhei (Ryuya Wakaba) who returned from the United States came to report that when Masaru Kawauchi took him to visit the hospital, an emergency patient was brought.The patient is actress Rena Sekirei, and the test result is cerebral infarction.After getting the consent of her husband and agent Emoto Hiroshi, Sanpin decided to carry out treatment immediately. Sanpin instructed Masaya Kawauchi to help, but was stopped by the head nurse Tsubata Reiko (Michiko Yoshise).After the operation, Sanpin learned from the emergency minister Kota Hoshimae (Yudai Chiba) that Masaru Kawauchi suffered from memory impairment.

Although Lena woke up after receiving treatment, she could barely speak and was diagnosed with residual aphasia.The actress' career could no longer continue, and Lian Na could not do anything and began to give up on herself.

Sanpin told Masaru Kawauchi that there were not enough manpower, so just do what you can, and directly talked to the dean Toshiyuki Todo (Junpei Yasui) to let Miyami also serve as a doctor for examination and diagnosis...

As the assistant of Sanpin (Ryuya Wakaba), Masaru Kawauchi (Hana Sugisaki), who suffered from memory impairment, participated in the operation. This incident caused an uproar. Masaru Kawauchi's chief physician Osako (Arata Iura) reported to Dean Todo (Junpei Yasui)) protested strongly: “This is extremely dangerous behavior.”The head nurse Tsubata (Michiko Yoshise) also agreed with this.Kawauchi Masaru kept Osako's words in mind, and then thought about it. First of all, don't worry, and find out what only you who have the sequelae can do.

At the same time, high school student Ryosuke Kamada (Ryuunosuke Shimamura), who was active as an ace at a strong football school, collapsed during the game and was sent to emergency treatment.The examination results showed that Ryousuke, who had damaged his right brain, was left with the sequelae of ignoring the left half of his body and losing all sensation on the left side of his body.

Ryosuke not only cannot see the left side, but also has difficulty walking straight due to severe symptoms such that all information on the left side is ignored by the brain.

Despite this, Ryosuke, who aims to participate in the national competition with his teammates, not only does not feel depressed, but also works hard to rehabilitate in order to return to the football field.

On the other hand, Sanping was worried about whether Kawauchi Ya, who suffered from memory impairment, was qualified to be the attending doctor, so he pushed her and said: “I am by your side.”Sanpin said“I will definitely support you as a doctor”. For some reason, Kawauchi Masa felt very uncomfortable.I don’t know what I think after reading the diary.

Sanpin (Ryuya Wakaba) hinted at the possibility of curing Miyabi (Hana Sugisaki)'s memory disorder, and also revealed the shocking past of “We Are Engaged”.Yaya was shocked by the sudden confession and hesitated whether to write this sentence down in her diary.The next day, Hoshimae (Chiba Yudai) took out another photo with San Ping, embarrassing San Ping.

There are rumors among the hospital staff that Tsubata (Michiko Yoshise) and Osako (Arata Iura) had a quarrel. I don't know whether it is true or not.Tsubata put the safety of the patient as his top priority and went to negotiate personally, believing that Ya should not be allowed to participate in the operation.Moreover, the nurses also protested against Tsubata, the head of the safety room. Hoshimae also believed that this was an act beyond his authority and protested to Toudo (Junpei Yasui).According to Todo, Tsubata is obsessed with patient safety for a reason...

Sanpin (Ryuya Wakaba) checked the brain of Miyabi (Hana Sugisaki) and found that she had no major damage that caused such a severe memory impairment. Both Sanpin and Miyabi were confused.But Osako (Arata Iura) pointed out that the judgment of three pins was wrong.Moreover, he also said that the three bottles he knew before were “Dangerous Doctor”.

Sanpin could not accept the test results. In order to confirm Miyabi's medical records with his own eyes, he found Osako.However, the secretary Mai (Erika Ikuta) said that Osako will not be around all day long, and just when he was about to give up, he met a 7-year-old boy who looked like a hospital patient in the hospital.The boy's surgery became the trigger for the fierce confrontation between Sanpin and Osako.

On the other hand, Miyabi met robotics researcher Makoto Kase (Mizuki Maehara).Kase was a patient with an aneurysm that was found to be likely to rupture in his brain.The annual risk of a brain aneurysm rupturing is only 1“, but if it does, it can leave severe disability and, in the most severe cases, death.However, if surgery is performed, there is a 4 to 10” chance that there will be sequelae.Faced with the cruel choice of probability theory, Kase, who had to raise his wife and young children, was entangled.Masaru patiently accompanied Kase, and in order to give him the best treatment, he also discussed with catheter expert Ayano (Okayama Amane).Then Ayano said something unexpected to Yaya...

The abbot of the temple, Narumi (Miyake Hiroshiro), lost consciousness while chanting sutras and was sent to the hospital.As a result of the examination, stagnant disease was found, which may cause cerebral infarction and cerebral hemorrhage after treatment. The attending doctor Masaru (Sugisaki Hana) suggested that Chenghai resign from all jobs.In fact, he was persuaded to quit, and Chenghai accepted the suggestion calmly, but his disciple Biting (Ryu Otomo) could not hide his uneasiness.

Chenghai's surgery is about to begin, and Sanpin (Ryuya Wakaba) appoints Ya as the surgeon.But Ya said that the blood vessels of depression are very thin and the surgery is very difficult, so it is not feasible for him now.“ Dr. Kawauchi can do it.”Sanpin's tone seemed to be sure that the operation would be successful. However, Mai (Erika Ikuta) told Masaru Kawauchi that it was best not to believe him too much. This sentence deeply attracted Masaru Kawauchi's attention.

On the other hand, Hoshimae (Chiba Yudai), who aims at the level of a general practitioner, asked Sanpin to also perform brain surgery, but was flatly rejected.Xingqian called doctors who did not have his own professional knowledge “professional idiots”, hoping to reduce the number of troubled patients, but three bottles of it rejected his idea.So Xingqian raised his voice in a rare move, and there was an atmosphere of disgust between the two people who were incompatible with each other.But in fact, there is some reason behind Xingqian's lofty ambitions...

Kentaro Yamamoto (played by Suzunosuke), who had been treated for cerebral hemorrhage in the past, was admitted to the hospital due to epileptic seizures.Because once he had a seizure, he was likely to have another seizure in the future, Yamamoto was prescribed anti-epileptic drugs.On the other hand, antiepileptic drugs are not recommended as prophylaxis in patients who have not had a single seizure.

It is said that Osako (Iura Arata) prescribed this medicine to Kawauchi Masaru (Sugisaki Hana) as a preventive medicine.Hearing this sentence, doubts about Kawauchi Masa's memory disorder emerged in Sanpin (Wakaba Ryuya)'s mind.Hoshimae (Chiba Yudai), who was entrusted by Tsuhata (Michiko Yoshise), asked Osako's subordinate Ayano (Okayama Amane) about what happened, but his doubts became deeper and deeper.
If Sanpin's idea is correct, then Osako told a “huge lie” to Kawauchi Masaru.Kawauchi Masaru couldn't believe that Osako had lied to him for a moment, but he found three bottles that proved his hypothesis and became angry.

At this time, Yamamoto began taking anti-epileptic drugs. In order to ensure adequate sleep, Yamamoto proposed to the company to reduce night shifts.However, the superiors, who lacked understanding of the sequelae, said that no special treatment could be given and that the daytime work should be taken off temporarily.Kawauchi Masaru made a bold move for Yamamoto.

Thanks to the addition of anti-epileptic drugs, Masaru Kawauchi (Hana Sugisaki) can now remember what happened the day before, albeit only in fragments.

Needless to say, Mori (Hanazumi Tani), Narimasu (Kayo Noro) and other members of the medical board who have always supported Kawauchi Masaru are also very happy.However, only Sanpin (Ryuya Wakaba) felt uncomfortable with the method of improving memory impairment and had a gloomy expression.

To celebrate, everyone came to the izakaya run by Takeshi Takami (Mantaro Koichi) as usual, and found that the taste of the food was stronger than usual.An examination was conducted at the suggestion of Masaru Kawauchi, and it was discovered that Takeshi had a tumor called meningioma in his brain. Affected by the tumor, his sense of smell decreased and the smell became heavier.Although surgery is possible, it is an extremely difficult operation because nerves are damaged when removing the tumor and there is a high possibility of losing the sense of smell.But without surgery, it will soon become life-threatening.As a chef faced with the ultimate choice...

On the other hand, although Masaru Kawauchi still remembered the memory of the previous day, he found many errors in the content.In the end, I almost got the wrong patient during the treatment and was so frightened that I stood still.Sanping said that this may be a memory error caused by memory swapping in the brain. Unfortunately, the treatment method is still unknown.

In order to rebuild the Kanto Medical University Hospital, Nishijima (Sake Miuyoshi) plans to use Mai (Erika Ikuta) from Ayano Hospital to launch a conspiracy to persuade Mai not to marry Ayano (Okayama Amane).But if this happens, Ayano Hospital, which is burdened with huge debts, will definitely collapse.Ayano does not understand Mai's true intentions and is confused as to why she suddenly broke off the engagement.

Ayano's father, Isao (Iida Motosuke), learned of his son's marriage and strongly opposed the abolition of medical care in sparsely populated areas for reconstruction.Ayano desperately tried to persuade, but there was nothing she could do.Among them, Hoon, who was visiting the hospital, suffered a head injury in a traffic accident and was sent to Hillyung Central Hospital.The operation was successfully completed with the help of Masaru Kawauchi (Hana Sugisaki) and others, but it left Isao with the sequelae of social mobility disorder and inability to control his emotions, so for a period of time, Ayano replaced Isao in the sparsely populated area.area clinics.

On the other hand, Masahiro Kawauchi recalled what Sanpin (Ryuya Wakaba) said about "We are engaged" and could not confirm with the Sanpin in front of him whether this was true.Moreover, she also remembered the time when she and Ayano went to an art museum and were confessed there!?

Kawauchi Masaru (Sugisaki Hana) recalled the past when she had dinner with Sanpin (Ryuya Wakaba), Ayano (Okayama Amane), and Mai (Erika Ikuta), and thought that Mai might be interested in her engagement with Sanpin.Understand something.

I asked Mai while having a dumpling party at her home. Mai knew that it was the memory of the first time they saw three bottles in Cape Town, South Africa.At that time, Kawauchi Masaru and Mipin did often move together, but that was a lie to avoid Ayano's approach.Mai didn't know the details about the engagement, and only San Ping knew the truth.Kawauchi Masa finally made up his mind to face Sanpin himself.

At this time, Kawauchi Masaru accidentally met Nishijima (Sake Mikado), and was startled when he saw Oshio Haruto (Kuroda Daisuke) of Uhara Construction walking next to Nishijima.Although I didn't know the reason, I felt great fear.San Ping discovered that something strange had happened to Kawauchi Ya after she came back, and listened to her words...

On the other hand, Kawauchi Masa heard from Mai whether Professor Osako had said anything to Xiaoya, and Kawauchi Masa went to find Osako (Arata Iura).

Osako didn't answer anything for a while, but taking something as an opportunity, he called out Kawauchi Masaru again and began to express all his thoughts.

Kawauchi Masaru (Sugisaki Hana)'s forgetful symptoms appeared again, and suddenly she didn't know who Sanpin (Wakaba Ryuya) was.Although it was only a mild attack this time, Osako (Arata Iura) explained Kawauchi Masaru's condition to Sanpin in detail, and told Sanpin that the operation was too dangerous and should never be performed.

A few days later, painter Shusaku Kashiwagi (Masaya Kato) suffered an epileptic seizure in the park and was taken to Hillside Central Hospital.Zhou Zuo suffered from the most serious brain tumor. After receiving all available treatments, he is now in a hopeless state.Soon, Shuzuo began to gradually lose his previous memories, and he even no longer knew about his wife Yoshimi (Mariko Akama).Seeing Shusaku's appearance, Kawauchi Masaru was also driven by the uneasiness that he would forget everything in the future...

On the other hand, Sanpin remembered the more detailed brain MRI images seen at Osako.The reason for Kawauchi Masaru's memory impairment lies in the area where people cannot undergo surgery“normansland”. If forced to perform surgery, it will be life-threatening.But if left unchecked and it happens again, it will lead to the same results.Then the only option is surgery...

Faced with Sanpin who was immersed in practicing surgery while struggling, Kawauchi made up his mind.

Masaru Kawauchi (Hana Sugisaki) collapsed due to a severe headache.The examination results showed that the old disease has relapsed. If this continues, there is a high possibility of consciousness disorder.The current situation is very urgent. Once cerebral infarction occurs, it is only a matter of time before it becomes life-threatening.Sanpin (Ryuya Wakaba) told Masaru Kawauchi, who had only a few hours of memory left, that if the symptoms continued to develop, he hoped that the operation could be given to him, but Masaru Kawauchi was determined and still did not have surgery.Unwilling to give up, Sanbo practiced hard in order to anastomose Normanslander's blood vessels below 0.5mm within a limited time.However, Tsubata (Michiko Yoshise) noticed Kawauchi Masa's thoughts and told her to do what you want.

Kawauchi Masaru has lost the memory of the past two years, and what happened today will be forgotten tomorrow——.Although she suffers from a serious disease such as memory impairment, she lives a positive and optimistic life by writing a diary every day and accompanying many patients.Will her today be forever disconnected from tomorrow? Kawauchi Masaru is in a life crisis, and Sanpin wants to save her.The future waiting for the two of them is-
