Obsessive-compulsive disorder.

For some people, obsessive-compulsive disorder is caused by doing something wrong, which leaves a strong impression in their mind.

In order to avoid making the same mistake again, I require myself to do a lot of repetitive actions to prevent the same mistake from happening again.

The light bulb was short-circuited because the switch was not pressed fully.

When closing the door, it was not closed properly and it opened again.

Of these two, which one is more likely to trigger obsessive-compulsive disorder?

The answer is Chapter 1.

Because it broke the light bulb and caused bad consequences.

Then next time, I will naturally pay attention to this problem so as not to make the same mistake.

Therefore, excessive attention becomes a pathological psychology.

The door being open is just the door being open, and it does not cause any bad consequences. At most, it will just let in some mosquitoes, but it will not leave a deep impression on people.

But Mrs. Matsushita.

Her actions indirectly led to the loss of a life.

This impact left an extremely strong impression on her mind, and was reflected in her behavior. When someone asked her for something, she was completely unable to refuse.

No matter how painful and tormenting it would cause her.

"But perhaps Mrs. Mitori is also the one who is suffering a lot."

After listening to Mrs. Matsushita's explanation of why she couldn't refuse her request, Tang Ze slowly spoke.

"ah?"

Mrs. Matsushita looked at Tang Ze in confusion when she heard this, her face full of doubts, not understanding why Tang Ze said that.

"Mrs. Mitori, aren't you acting very greedy? That's what Mrs. Katori said."

After a pause, Tang Ze changed the subject and said, "If that's the case, the one who accepted it might also be hurt."

"How could... that be..."

“You…you…”

When Mrs. Matsushita heard what Tang Ze said, she seemed to understand something and trembled so much that she couldn't even speak complete words.

"Mrs. Matsushita, because of your previous experiences, you have become a person who always responds to requests. However, for Mrs. Mitori, who is unaware of the inside story, your generosity has caused great damage to her self-esteem.

Of course, Mrs. Mitori might have been jealous of you, or even felt inferior to you, and the result was…"

Tang Ze sighed and said, "I'm deliberately making things difficult for you because you're so generous and give me everything.

That's why he became even more greedy and demanded more, acting like a shameless villain."

One party becomes extremely generous because he cannot refuse others, while the other party has a strong self-esteem and is unwilling to accept what others give, and regards it as an "insult."

These two people really have the worst compatibility.

Thinking of the time when the other person asked her for her mother's scarf while they were shopping, she said excitedly: "What I give her is hers. It's her right to do with it as she wishes. I really think so!

But I think the things she asked for will be cherished and used by her."

However, this was not the case. On the contrary, Sanae Sanori sold all those items.

Mrs. Katori's confession and apology shattered her only fantasy.

It was intolerable, especially for a relic of my mother's, the scarf was a treasure she cherished.

So, she then went to Sanae Mitori's house.

The other person had a cold at the time and was resting on the sofa with a mask on. She came and stated her purpose, hoping to get the scarf back and not pursue the things she had given her before.

But the other party asked her to buy it back with money.

Moreover, Sanae Mitori mocked her with harsh words, saying that she hated people like her. She just praised something lightly and gave it to her directly.

He was showing off as if he had given her a great gift, and his condescending attitude made her very unhappy, so she kept asking her for things.

Sanae Mitori's attitude shattered Mrs. Matsushita's last bit of fantasy, but she just wanted her scarf back, which was her mother's relic.

Then she pleaded and said sorry while rushing towards Sanae Mitori, asking her to return the scarf to her.

The two struggled and entangled as they entered the house, and Mrs. Matsushita finally overpowered the sick and weak Sanae Mitori and pressed her down on the sofa.

The other person was wearing a mask and had the scarf around his neck. Mrs. Matsushita kept pulling the scarf while trying to snatch it away. When she came to her senses, the other person was already dead.

Afterwards, she retrieved her scarf and quickly escaped through the glass sliding door.

"Did you intend to kill her?" Takagi asked with pity as he looked at the sobbing Mrs. Matsushita.

"I have no idea!"

"have no idea?"

"I just... I just felt very angry and thought she was hateful. I couldn't let go of my hand that was strangling her at that time." Mrs. Matsushita said this while choking.

The two of them waited patiently for Mrs. Matsushita to adjust her mood, and finally watched her take out the scarf made of gray squirrel fur from the storage box.

"Can't throw it away?" Tang Ze asked.

"Isn't that only natural? After all, this is my mother's legacy."

Mrs. Matsushita handed the scarf to Tang Ze and said with a self-deprecating smile, "Even if it's a relic, it's just an ordinary item. I clearly warned myself not to be too attached to material things...

Otherwise, tragedy will happen... I already know this, but still..."

"Then let's go."

"Yes." Gao Mu nodded and looked at Mrs. Matsushita and said, "Could you please prepare it?"

"Detective Takagi, as for Mrs. Matsushita, let's have her turn herself in later."

Tang Ze held the scarf and said something that surprised both of them.

"Eh?" Takagi looked confused. "Detective Karasawa, what are you talking about?"

The criminal has been caught, and the normal procedure is to have him clean up and take him back to the police station, but what is happening now?

"Well, after all, we still have to catch the real murderer." Tang Ze smiled at the two confused people and said so.

"What!?"

Tang Ze's words startled the two of them. Even Mrs. Matsushita, who was sobbing beside them, stopped crying because she was too shocked and looked at Tang Ze blankly.

"Don't you realize? If this scarf is the murder weapon, it's a bit too thick."

Tang Ze showed the fur scarf in his hand to Takagi. The furry scarf was made of gray squirrel fur and was about six or seven centimeters wide.

"If this was placed over Mrs. Mitori's mask, it would have caused her to go into temporary shock, which is probably true."

Tang Ze looked at the scarf, his eyes deep and solemn: "But this is completely inconsistent with the strangulation marks on Sanae Mitori's neck!!"
