Living in Tokyo, all I want to do is laze around.

The second Hanabi's personality is completely opposite to that of Hanamaru Hanabi.

"Don't you think it's completely opposite to your wife's original personality?"

"Yes."

"Alright, now that we understand this, let's analyze why two opposite personalities suddenly appear."

Kai Uesugi looked down at the endless stream of cars from high above, listening intently to the voice on the other end of the phone.

“I have treated many patients with mental illnesses before. There was a 64-year-old taxi driver who had been selected as the company’s best driver for 30 consecutive years. In those 30 years, he had zero negative reviews and zero accidents, and he had encountered all sorts of strange customers from all walks of life.”

"Some people are never so friendly, mostly young men in jackets with tattoos. They nitpick and verbally abuse the driver because the fare is too high, even though they know that the fare is not controlled by the driver."

"They weren't doing anything wrong, they were just venting their emotions on him."

"Despite such unreasonable accusations, the driver could only endure it and repeatedly bowed and apologized."

Thirty years of forbearance have made this driver seem to have no reaction to passengers' accusations. When passengers curse him, he apologizes; when passengers hit him, he apologizes again and again, just to avoid making mistakes and to be selected as the company's outstanding driver at the end of the year.

"When he was 63 years old, the same year he held the record for 30 years, the company's senior management absconded with the money, causing the taxi company to run into financial difficulties and its cash flow to break down. As a result, this driver naturally lost his job."

"He was too old, and no other company was willing to take him in. He was too focused on his work and had no wife or children for decades."

"After being laid off from his position as an excellent driver for thirty years, what kind of personality does Mr. Uesugi think he ultimately became?"

When asked by Dr. Nakamura, Kai Uesugi remained silent for a moment before replying:

"He should just give up, since he has nothing left."

"It's not that he had nothing. He used his savings of thirty years to buy a detached house in Shibuya, Tokyo, so he wouldn't have to worry about money for the rest of his life."

"However, he developed a serious mental problem. Because he was no longer eligible for the award for outstanding driver, he became irritable, drank heavily, and enjoyed abusing animals. In the end, he couldn't stand the children playing around his house, so he kidnapped a five-year-old neighbor's child and was imprisoned."

"This is completely different from his forbearance in the first half of his life. We usually call this kind of psychological change in personality a rebound effect."

"I wanted to quit drinking and smoking, but after suppressing myself for a few days, I became more indulgent afterward. I tried to escape the pain, trauma, and distress, but because I suppressed myself too much, these symptoms returned in a more negative way."

rebound effect...

Kai Uesugi roughly understood what the doctor meant on the phone. He placed his left hand on the metal balcony railing, feeling the slight coolness coming from above.

"Doctor Nakamura means that my wife experienced this rebound effect?"

"The example is to convince you that the driver was a real patient I treated. It's hard to say about your wife's condition, but think carefully about what her second personality showed."

"Is this second personality trait a manifestation of your wife's subconscious desires?"

"It's just that one personality trait can restrain oneself, while the second personality trait believes that some things must be held in one's own hands."

Words, one by one, traveled from the other end of the phone to my ears.

As Uesugi Kai gazed at the constantly flashing neon lights of the city, he couldn't help but ponder.

He had long believed that the existence of Black Flower Fire was the result of the sins of another version of himself in a parallel world.

But now that I think about it, Black Fireworks is more like a manifestation of Hanabi's long-suppressed desires deep inside her.

She liked herself too much, wanted to possess herself too much, and wanted to respond to her too much.

Dr. Nakamura then said on the phone:

"Following this line of thought, I believe you can understand why your wife suggested separating for ten days, right?"

Hanabi often says, "Kai-kun, you must remember Hanabi."

To make herself remember her, the woman deliberately dressed herself, made breakfast and a lunchbox for her the day before she left, and helped her take a bath and did naughty things with her that night.

She deliberately stopped halfway through the last thing.

Kai Uesugi remembers that he could only go to the toilet to take care of the rest of his business that night.

What she wanted was for herself to miss her both mentally and physically.

Black fireworks represent the ultimate expression of desire in fireworks.

It all stemmed from the timid girl herself.

Kai Uesugi felt he understood, but he still only had a vague concept of some things.

"I see......"

"Yes, but Mr. Uesugi, you should also be careful. Your wife is currently only experiencing a change in personality. If the situation worsens, she may even develop a second personality. At that point, the mental inconsistency of her personalities will not be a simple matter."

"What harm could it cause...?" Uesugi Kai asked hastily.

"Mr. Uesugi, you need to know that dissociative identity disorder is a mental illness. It is not a simple illness where different personalities can take over the body and coexist peacefully. It is very likely that the person will go crazy in a state of confusion, lose their intelligence, lose their rationality, and become unable to control themselves. Therefore, you should not provoke your wife too much."

"Does Mr. Uesugi have any further questions?"

“That’s all.” Uesugi Kai suddenly lost in thought.

"Please don't worry too much. Your wife is currently in good health. If possible, please try to find out what she wants most right now. Desires need to be released."

......

beep.

After a brief, silent tone, Uesugi Kai put away the phone.

The cold wind blew across his face, and he felt even more weary.

--------

My thoughts drifted away from the night scene.

Kai Uesugi snapped out of her daze, her mind now completely free of the absent-mindedness she had felt the day before.

Last night he only had a vague idea, but now he truly understands.

He is now standing at the entrance of Mimi Cafe, with Hanamaru Hanabi right beside him.

From downstairs to upstairs, Hanabi Hanabi herself appears.

"Kai-kun...aren't you going in...?"

Kai Uesugi kept recalling what Dr. Nakamura had told her yesterday. Turning her head to look at her familiar face, she already had a way to verify that idea.

So, I asked her:

"I have a day off tomorrow... Shall we go on a date?"

"OK..."

Hanabi Hanamaru blushed and lowered her head, looking as shy as a young girl on her first date.

"Where's the other you? Won't she come out?" Uesugi Kai could tell this was an expression of her happiness.

“She… doesn’t seem to like dating much…” Hanabi Hanabi looked up at him.

"She doesn't like dating me?"

"Hmm... I guess you mean you think dating is boring... and you'd rather just go with Kai-kun..." Hanabi Hanamaru blushed again.

How could Kurohanabi not like dating?

Uesugi Kai thought to himself, a vague guess forming in his mind.

Either Hanabi wanted to go, which led to her developing a dislike for dating.

They can talk to each other because they are the same person, so they complement each other.

What Hanabi wants, Kurohanabi won't fight for.

If Hanabi can't get it, Black Hanabi will come out and get it for her.

For example, that thug from yesterday, because Hanabi was completely unable to deal with him, Kuro Hanabi came out and took care of him.

They are essentially still the same person.

They simply complement each other in ways that neither of them can do.

The danger Dr. Nakamura mentioned is that Hanabi's second personality might exhibit Hanabi's own emotions, potentially leading to a split personality.

After figuring this out, Uesugi Kai felt inexplicably excited.

Because this means that the wife has always been guided by her own thoughts.

It was always the Hanabi-chan he knew.

It's just that she's sick, and sometimes she wants more from herself.

That is the significance of the existence of black fireworks.

Uesugi Kai decided to verify this claim again before entering the coffee shop.

"Firework Sauce".

"Um..."

"Before... the other you often came out and even made breakfast for me? I feel like the food tastes exactly the same, just like your cooking. Do you two... cook the same way?"

Hanabi Hanabi looked at him without saying a word.

Why isn't Hanabi answering?

Hanabi Hanamaru suddenly stood on tiptoe, placed her hands on Kai Uesugi's shoulders, and whispered to him, "I'll tell you a secret, Kai-kun... actually, my other self can't cook. It's Hanabi who does all the cooking for you."

Uesugi Kai was taken aback, then secretly delighted.

"Does Hanabi like cooking...?"

"Hmm...because Kai-kun will enjoy the meal...and Hanabi will feel a sense of accomplishment..."

Just as I thought!

Hanabi likes to cook for Kai-kun, so Black Hanabi doesn't have the attribute of being able to cook.

Because she cannot control her own thoughts!

Black Flower Fire is a personality trait that only emerges when she wants something but can't get it.

In order to attract Kai-kun's attention, she changed her style and way of dressing.

Knowing that Kai-kun likes Se-se, she wanted to help him, but she was too embarrassed to offer it herself, so Kuro Hanabi took the initiative to ask him to help!

They are all the same person!

A surge of joy welled up in Uesugi Kai's heart, and he couldn't help but smile. He asked the cute girl who had lowered her hands to her shoulders and put her heels back down:
