"Thank you, thank you very much for your assistance."
Early the next morning, the boy and Karasuma, along with two detectives, came to Kanda Akina's house.
With the help of Kanda and his wife, they found the thick diary with various stars and Q-version animals painted on the cover that Akina Kanda had placed on the desk in her bedroom.
Ever since yesterday evening, when Kokarasuma noticed the clue left on Akina's hand before her death due to Hatoyama Keiko's unintentional reminder, they went to the Metropolitan Police Department as soon as possible this morning and rummaged through the Some of Kanda Akina's personal belongings used at school were temporarily kept at the Metropolitan Police Department as possible evidence by the police.
But the diary of Kanda Akina in Karasuma's memory was not found, and then they came to Kanda's house.
"Officer, can Qiunai's diary really help you catch her murderer?"
At the door of Kanda's house, Mrs. Kanda handed the diary to the boy and looked up at him with a haggard expression.
Unable to bear the heavy blow of her daughter's death, Mrs. Kanda, who was not yet forty years old, seemed to have suddenly aged several dozen years in the past two days, with an extremely haggard and withered face.
"Don't worry, Aunt Kanda, we will definitely catch the murderer."
Seeing this beautiful woman who was originally gentle and kind-hearted now look like this, Karasumaru's heart throbbed again.
"It is the duty of the police to catch every guilty criminal. Mrs. Kanda, please wait a little longer."
With a professional smile on his face, the boy nodded slightly to Mrs. Kanda, then turned and left.
Returning to the police car, the boy quickly opened the thick diary in his hand. Although it seemed a bit abnormal to look at a girl's diary like this, the boy would not be bothered by the special situation now.
Since Akina-san left this clue at the last moment, it means that there must be information in this diary that Akina-san wants to convey to Karasumaru.
To be honest, the boy was a little surprised when he realized this.
Because this also means that Akina-san seems to have predicted her own murder in advance?
No, this possibility should be unlikely.
But at least, she shouldn't be too surprised by her murder. When the poison happened, she might have guessed the reason why she was poisoned, and even guessed that the person who poisoned her was the same as her. In a class, right there.
As a result, Akina-san did not dare to directly tell Karasumaru, who was right next to her, her guess.
Not to mention the neurological disorder caused by aconitum toxin, Akina-san was already unable to speak normally at that time.
Even if it was possible, the murderer's "accomplice" was also present at the time. Akina-san was afraid that doing so would further stimulate the murderer and bring unnecessary danger to Karasuma.
Therefore, she chose to use her last strength to secretly leave such a clue in Karasumaru's hand.
Her diary should contain information that would allow the police to find the murderer.
The boy did not start browsing from the front. Instead, he started reading from the latest place and read forward. Little Karasuma also moved his head skillfully.
The sound of turning the pages of a book sounded from time to time, and soon the two found the clue they wanted, a clue that surprised both of them, but was consistent with the current investigation situation.
In Akina's classmate's diary, it was written in extremely detailed and clear terms that she had feelings for the club advisor of her drama club, Mr. Ryuhei Aizawa, which a student should not have.
The specific cause seems to be two months ago.
After discussing the script of a play with Mr. Ryuhei Aizawa, and rehearsing privately with each other as the male and female protagonists, Akina suddenly found that she seemed to have a crush on this handsome young teacher with a gloomy temperament like a literary youth. Good impression.
However, one of these two people is a teacher and the other is a student. More importantly, Aizawa Ryuhei is already married and has children.
This is absolutely forbidden love.
But emotions are often beyond the control of human reason, especially for a female high school student who has never had a similar experience.
The more Akina-san is suppressed, the heavier her feelings for Aizawa Ryuhei become.
Since more than two months ago, the relationship between Akina-san and Aizawa Ryuhei has become closer and closer, and there seems to be a faint tendency to go beyond the normal teacher-student relationship.
In Akina's classmate's diary, it was even written that she and Aizawa Ryuhei met alone outside school twice.
Although the diary stated that the two people met in public places such as coffee shops or barbecue restaurants and did not take any further actions, this was actually...a very unethical behavior.
At the end of the diary, Akina-san did not specify how she was going to deal with this forbidden relationship. It seemed that she had not made up her mind until the end.
"Is that so..."
After sorting out all the information in the diary, Karasuma was a little dazed. She stared blankly ahead. After a long time, she sighed deeply.
"No wonder Qiuna was so embarrassed on the day she was killed. She refused to tell me no matter how I asked. Is that why..."
Karasumaru suddenly felt a little sad, feeling sorry for herself.
Because in the past two months, she didn't notice any changes in her good friend. I'm afraid it wasn't just her, but even Akina's parents didn't notice the changes in their daughter.
It was not until the last day that Karasuma finally noticed something unusual.
If she could have noticed it earlier, if her attitude could have been tougher that day, would it have been...
"There is no use regretting it."
As if aware of her inner emotions, the boy closed the diary, handed it to the two detectives in the front row, and spoke.
"Being affected by this kind of emotion will only make us worry more about gains and losses when we face similar situations in the future.
Now that things have happened, all we can do is learn lessons, gain experience, and then move forward. "
"I know……"
After receiving such an education, even though she knew that the boy was using his unique method to enlighten her, Karasuma still felt sad.
"You dead piece of wood..."
The boy didn't pay attention to her little complaint. After he finished speaking, he ordered the two detectives:
"Plans have changed. Before we go back, we will go to two places first."
Akina is a very meticulous person. In her diary, she not only wrote that she and Aizawa Ryuhei had two private meetings outside of school.
She even wrote down the names of the coffee shops and barbecue restaurants where they met twice.
This facilitated the boy's investigation. He needed to go over to confirm the situation.
