The old lady recounted the past of Tsumabuki Minami. Because Tsumabuki Minami and Nakamura Yue were close, he would often come to their house for meals, especially enjoying the dumplings she made, and would also confide in her.

“I felt that the child needed to see a psychologist, so I asked my eldest granddaughter to help find a psychologist. She pretended to be a guest of my family and chatted with Mu Nan for a while. Later, the doctor said that Mu Nan had a very serious suicidal tendency.”

Yue Nakamura explained, "My eldest niece is a doctor, and her boyfriend is a psychologist."

"Did Namu Nan go for treatment?" Ye Qingqing asked.

Nakamura Yue shook her head. "I brought it up with him, but he felt he had no problem at all. We even had an argument about it."

Ye Qingqing frowned. A psychologist would never say anything carelessly, and she also felt that Tsumabuki Minami's emotions were indeed very strange.

"Did your niece's boyfriend say how Mu Nanjun's mental illness was caused?"

“He said that family environment was the main reason. Someone must have said these things, and not just once or twice, which made Mu Nan feel very guilty, and this feeling was deeply ingrained.”

Yue Nakamura looked regretful. Minami Tsumabuki was his good friend, and he didn't want anything to happen to him, but he couldn't help.

And he couldn't understand it either.

“I’ve been to Kinan’s house. His parents and brothers are all very open-minded and kind people. They are very good to Kinan and have never blamed him for Mai’s illness. So I really don’t understand why Kinan would have such strange ideas. Who is talking nonsense? It’s really disgusting.”

Ye Qingqing frowned even more. It seemed that she wasn't the only one with such thoughts. The person who caused Tsumabuki Minami's mental illness was probably not his parents or brothers.

The first person she thought of was Mai Tsumabu, that strange girl.

After saying goodbye to Mrs. Nakamura, Yue Nakamura saw her off in a taxi. When she returned to the hotel, Lu Mo had already returned, bringing several photocopies.

“The other medical records are all quite ordinary, but I find these few a bit interesting. Take a look.”

Lu Mo handed her the photocopy, which had a Chinese translation. He explained, "This was written by Mr. Inukai. He spent most of the day looking for it for me."

Ye Qingqing looked at the medical records carefully. They were not from the same year. The earliest one was six years ago, when Tsumabu Mai was eleven years old and still a child.

"The patient was sleepwalking. Her mother said she saw the patient run to the back mountain at night, wearing only pajamas, which led to her severe cold."

Another medical record from five years ago describes the same situation: Mai Tsumabu sleepwalked in the middle of the night, went to the back mountain, and then came back on her own.

The remaining two records are from four and three years ago, respectively, both of which showed that sleepwalking at night worsened the condition, but there are no records from the last two years.

“She hasn’t sleepwalked in the past two years. The doctor analyzed that it might be because her body is too weak, which is why she can’t move. But the doctor also thinks that Mai Tsumabu isn’t sleepwalking, but more likely suffering from hysteria,” Lu Mo said.

Why is it called hysteria?

Ye Qingqing found it strange. Hysteria and sleepwalking are completely different illnesses. In folk medicine, hysteria is often mistaken for possession by a ghost because the patient behaves completely differently from usual and may even say things that would never normally be said. People can't explain it, so they simply assume it's possession by a ghost.

In fact, modern medicine cannot explain some hysterias. Ye Qingqing thinks that some are hysterias, while others may really be possession by ghosts.

A thought crossed Ye Qingqing's mind, and she asked, "Is it related to those animals that died mysteriously?"
