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.
