In fact, Yusaku Kudo didn't say anything particularly important.
The so-called usefulness was mostly supplementary details regarding what Yuu Hoshimiya had said.
For example, although Yusaku Kudo and Toichi Kuroba knew each other's identities, they hadn't acknowledged each other.
Therefore, Conan and Kid had never known that the two were cousins.
Another example was that after Toichi Kuroba faked his death, he hadn't contacted Yusaku Kudo. Yusaku Kudo only guessed that Kaito Kid was Toichi Kuroba, but had no evidence.
Yukiko basically didn't participate in their conversation.
She wasn't clear about many things regarding the Kudo family and the Kuroba family, and Yusaku Kudo hadn't told her.
Although they were nominally husband and wife, in reality, they had always lived their own lives, only having some overlap in their circle of friends.
However, although she didn't speak much, she kept getting closer to Yuu Hoshimiya during the chat.
By now, the distance between the three was about the same.
Yukiko and Yuu Hoshimiya seemed even closer.
If someone who didn't know them saw this, they would definitely think that Yuu Hoshimiya and Yukiko, who looked about the same age, were a couple, and Yusaku Kudo was their elder.
Yuu Hoshimiya faintly felt something strange, but Yukiko's acting skills were too good, plus Yusaku Kudo didn't show anything, so he just took it as his illusion.
Yusaku Kudo actually wanted to show something, but he and Yukiko had an agreement long ago.
Whether for himself and his son Shinichi Kudo, or out of keeping his promise, he had to pretend not to see Yukiko's little actions now.
Unless Yukiko went too far, he would speak up to remind her.
But the chances for him to remind her were not many. After returning to the United States this time, Yukiko would definitely propose a divorce and tell Shinichi Kudo the truth.
Then she would return to Japan alone to seek true love.
Thinking of this, Yusaku Kudo instantly felt the food wasn't tasty anymore.
After getting to know each other and personally confirming that Yuu Hoshimiya wasn't a bad person, Yusaku Kudo felt relieved.
The wife wasn't real, but the son was genuine.
Without confirming what kind of person Yuu Hoshimiya was with his own eyes, Yusaku Kudo wouldn't feel at ease with such a mysterious man hanging around Shinichi Kudo.
After a somewhat strange but harmonious dinner, Yuu Hoshimiya parted ways with the two.
Before leaving, Yukiko was somewhat reluctant, but she hid her emotions well.
Since Yusaku Kudo kept the agreement of that year, she wouldn't be a treacherous person and embarrass him.
Even if the fiery feelings in her heart almost overflowed, the sexy lady with long chestnut curly hair held back.
After finding an excuse to exchange contact information with Yuu Hoshimiya, she returned to the hotel with Yusaku Kudo.
After returning to their respective rooms, Yukiko immediately packed her luggage and booked a flight to the United States that night.
Yusaku Kudo felt bitter inside, and also began to pack luggage and buy flight tickets.
He still had things to do in the United States and couldn't stay in Japan for long. Rushing back so quickly should have made him happy, but he couldn't be happy no matter what.
The magical protagonist halo was at work all the time. When Yukiko and Yusaku Kudo boarded the flight to New York, Conan seemed to feel something and recalled things from his childhood.
In his memory, his parents' relationship was very thin, and the two had never slept in the same room, but they were really good to him.
In his memory, his father was either conceiving his mystery novels in the study every day or going out to collect writing materials.
And his mother was a superstar, rushing to announcements every day, either filming or appearing on shows, never at home.
When Conan could live alone, the two used the excuse of developing in the US and left Japan.
Actually, Conan had become suspicious long ago. He secretly collected hair from Yusaku Kudo and Yukiko for a paternity test.
The result could be said to be a mix of joy and sorrow.
He was Yusaku Kudo's biological son, but not Yukiko's.
Actually, without a paternity test, it could also be confirmed that Conan was Yusaku Kudo's biological son.
The two were almost carved from the same mold, as were Toichi Kuroba and Kaito Kuroba.
In Conan and Kaito Kuroba, no trace of Yukiko and Chikage Kuroba could be found at all.
Yusaku Kudo and Toichi Kuroba were identical twins, resulting in the four of them looking almost exactly the same.
After discovering that Yukiko was not his biological mother, Conan didn't make a fuss.
He wasn't old at the time, but he already understood many things.
Although he wasn't clear about what exactly was going on between Yusaku Kudo and Yukiko, he understood that having a mother was better than not having one, whether for him personally or for the Kudo family.
Moreover, Yukiko treated him well, and after getting along for these years, there were still feelings.
Being severely pranked this time, he was angry at first, but didn't really take it to heart.
Learning that Yusaku Kudo and Yukiko came back specifically for his affairs, he even felt somewhat happy and joyful.
However, Conan would never have guessed that this would be the opportunity for his happy family to turn into a single-parent family.
The next day, Yukiko, who arrived in New York, immediately took action.
Property division, reasonable explanation to the outside world, confessing the truth to Conan, etc., were completed by her one after another.
Looking at Yukiko's exaggerated mobility, bitterness surged in Yusaku Kudo's heart again, but he still cooperated rationally.
After all, the two were at most good friends; there were feelings, but not much.
And continuing to pester would be bad for both.
Given Yukiko's character, if he really did that, she would definitely fight him to the death.
That would be truly difficult to end.
Because there was a plan when they faked the marriage, it was handled quite quickly.
In just one day, Yukiko returned to being single, and then flew back to Tokyo alone again.
Conan didn't know about the divorce and the truth of that year for the time being.
Yukiko planned to tell him face to face after returning to Tokyo, and by the way, continue to let Conan board at the Mouri Detective Agency.
It could be considered the last thing she, a mother without blood relation, did for her son.
Tokyo, Narita Airport.
The chestnut-haired beauty with an enchanting and tall figure dragged her suitcase, humming a little tune happily, and came to the exit.
"Yuu-kun, I'm here..."
Looking at the bright sunshine, Yukiko took off the sunglasses covering most of her pretty face, and whispered with a faint smile at the corner of her mouth.
The moment she took off her sunglasses, many passers-by who were already attracted by her graceful figure stopped one after another, showing expressions of admiration and longing.
Some star chasers even recognized Yukiko, the international diva who had retired for many years.
But before these men could come up to strike up a conversation or ask for autographs, Yukiko had already gotten into the special car arranged long ago.
Yukiko had quite a few connections in Tokyo; after all, she grew up here and became famous from here.
Not only was the pick-up car arranged, but even the place to stay was settled.
Tokyo, City Center.
On the 27th floor of the tower apartment, three high-end apartments that had been vacant finally welcomed their owner today.
Undoubtedly, the person who bought them was Yukiko Fujimine.
After completing the procedures and returning to single status according to the agreement, Yukiko not only brought back her property but also changed her name back.
Through connections, she found out where Yuu Hoshimiya lived now.
Then with a wave of her hand, she bought the entire floor above the 26th floor.
Buying three rooms at once wasn't showing off wealth, but because she really needed them.
One for living, one for a cloakroom, and the last one for storage and specifically for disguise.
As a big star, Yukiko had a lot of clothes and needed a dedicated cloakroom.
Not only Yukiko, most rich people have dedicated cloakrooms.
Because Yukiko liked disguise, she needed more clothes and props, so she needed an extra room.
Although she only brought one suitcase today, in fact, there were two more suitcases of personal items to be sent from the United States later.
With Yukiko's wealth, many things didn't need to be sent back and forth specifically; just buy them when needed.
But there were also some personal items that were hard to buy, or she was used to using.
Two suitcases were really not much; compared to all items, they occupied less than one-tenth.
As for those unnecessary personal items, she also disposed of them.
If not handled properly, maybe one day they would flow out and be bought by crazy fans at high prices to do disgusting things.
Her choice to fake marriage with Yusaku Kudo and retire from the stage also had this reason.
Besides where Yuu Hoshimiya lived, Yukiko naturally knew about Yuu Hoshimiya's affairs with women.
But not deeply; she only thought that besides Sonoko, he was dating Ran and Seimi Asai at the same time.
Before meeting, Yukiko felt puzzled and incomprehensible, but after meeting Yuu Hoshimiya, she instantly understood why several women were willing to date Yuu Hoshimiya at the same time.
Even though Ran, Sonoko, and the others were top beauties, Yukiko was still confident in snatching Yuu Hoshimiya.
Wonder if she would still have this confidence when she learns the truth.
This intelligence was investigated by the Kudo couple after learning of Yuu Hoshimiya's existence from Conan; unexpectedly, it was used by Yukiko in this way now.
After simply tidying up the residence, Yukiko brought a gift and went downstairs directly to visit the neighbors.
Visiting neighbors was just an excuse; in fact, she wanted to see Yuu Hoshimiya quickly.
Unfortunately, today was a rare commuting day; Yuu Hoshimiya and Ran both went to school.
Seimi Asai also went to the Suzuki Manor to learn magic-related matters. No one was home, so Yukiko didn't even enter the door, let alone see Yuu Hoshimiya.
Eri Kisaki in 2601 was there; the sign of the Kisaki Law Office at the door was grand and conspicuous, indicating it was open for business.
Yukiko thought for a while and decided not to meet Eri Kisaki, this good friend and old classmate, for the time being.
After all, she planned to snatch a man from the other party's daughter; should she say it or hide it when they met?
If she knew Eri Kisaki was also Yuu Hoshimiya's woman, and even with Ran, she probably wouldn't think so.
Unfortunately, even the smart, clever, and knowledgeable international movie queen Yukiko Fujimine would absolutely not guess the mother-daughter donburi point before witnessing it with her own eyes.
Returning to her home, Yukiko dialed Conan's phone.
Since she didn't see Yuu Hoshimiya, she planned to solve Conan's matter first.
This time she was smart; to avoid not seeing anyone again, she called in advance to confirm if Conan was at home.
Because of Fumiyo Edogawa's appearance, Conan couldn't continue boarding at the Mouri Detective Agency these days and returned to Professor Agasa's home.
He should have gone to school today, but because he caught a cold from being pranked a few days ago, he didn't go and was recuperating at home today.
Confirming Conan was at Professor Agasa's home, Yukiko rode a motorcycle directly to find him.
"Mom, you came back quite fast this time... cough cough..."
Conan coughed while speaking to Yukiko, who was wearing a black leather outfit.
The night before yesterday, suddenly recalling his childhood, he called the Kudo couple.
First was to ask how the talk with Yuu Hoshimiya went, and second was to ask them to send him back to the Mouri Detective Agency.
Kogoro Mouri was unreliable, but the identity of a detective was really useful.
Although no intelligence on the Black Organization had been investigated yet, Conan still wanted to continue following Kogoro Mouri.
Unexpectedly, after the call connected, he learned the news that the two had to fly back to the United States immediately.
Saying there was an emergency...
At that time, Conan almost got really anxious. If Yusaku Kudo hadn't said that Yukiko would return soon and personally help him get back to Kogoro Mouri, he would have planned to run to the United States again.
Conan thought this 'soon' would be at least a week. Just as he was sick now and planned to rest for a few days, he didn't expect Yukiko to come back after only one day.
Yukiko flipped her hair and shook her index finger, "How many times have I said it, call me sister~~"
"Hai hai..."
Conan was listless, too lazy to bicker with his mom who liked to act young.
Seeing him like this, Yukiko put away her playful look and said seriously for once: "I'm serious this time. Although it's best to wait until you recover, I think you should be able to withstand it, Shinichi."
Conan's brain, which hadn't shrunk, started working instantly, keenly sensing that Yukiko seemed to be about to lay her cards on the table with him.
No wonder he suddenly recalled things from his childhood two days ago; was it because of this...
Although a staunch materialist, Conan believed in his intuition very much.
Many times when reasoning fell into a predicament, it was the intuition in his heart that helped him.
"Shinichi, listen well."
Yukiko didn't avoid Professor Agasa either; friends around would sooner or later know about her and Yusaku Kudo's affairs.
The sexy lady in leather took a deep breath and said decisively: "Actually, you are not my biological son."
The atmosphere fell into silence.
The next moment, Professor Agasa let out a surprised sound.
Instead, Conan looked calm and unruffled.
He said lightly: "Actually, I knew it long ago."
"Eh? Shinichi, you knew it long ago? Did Yusaku tell you?"
This time it was Yukiko who was surprised.
Although she was smart, she was still far behind the Kudo father and son.
"Cough cough... no."
Coughing twice, Conan endured the discomfort and briefly explained how he discovered it.
"So that's how it is... As expected of Shinichi, really amazing, discovering the truth at such a young age."
Yukiko sighed with emotion after hearing it, and at the same time felt a sense of relief.
Since Shinichi Kudo knew it long ago, then the next things would be easier to say.
