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

Kai Uesugi turned around and looked at himself in the mirror. In the mirror, Hanabi Hanabi was smiling gently at him from behind. She was beautiful... The girl's warm smile made him feel a strange pang in his heart, and even the light white shirt he was wearing seemed to have a bit more weight to it.

From now on, she will have to rely on herself.

This is what is called responsibility.

Kai Uesugi looked at himself in the mirror, and at Hanabi Hanabi smiling behind him in the mirror.

"...As expected, I still can't bear to see you become an artist."

"Kai-kun...have you figured it out?"

"Actually, I was reluctant to let you go from the very beginning... But then I thought about it and realized that if I could see the fireworks shining brightly on the stage, it would be a very happy thing."

Hanabi Hanabi moved closer to him, her upturned face almost touching his.

"Then... Kai-kun isn't happy right now?"

"It's because I can't bear to give up my current happiness that I don't want Hanabi-chan to be too far away."

Uesugi Kai smiled and, taking her by surprise, pulled the girl into his arms.

Hanabi struggled slightly at first, but when she realized she couldn't break free, she slowly leaned against his chest.

Kai Uesugi loved the feeling of holding her. Her body was soft and small. After holding her for a while, he would want to pick her up, press his forehead against hers, and pamper her.

"The good morning kiss hasn't even started yet," Uesugi Kai suddenly said.

"Kai-kun is thinking about bad things again."

"Let me kiss you."

"No." Hanabi Hanamaru turned her face away.

"good."

"Don't don't."

Hanabi Hanabi blushed and struggled to break free from his embrace, running out of the bedroom.

Kai Uesugi looked at the door she had run out through and smiled.

Today was another peaceful day. After Hanamaru Hanabi made breakfast, the four of them ate together in the living room.

Aiyi and Qian Aiyi recently went to a taekwondo gym, but the two little ones, especially Aiyi, lost interest after trying it twice and are currently staying at home.

"I didn't take you guys out the other day, I hope Aiyi isn't upset?"

No, you won't.

"How about your brother takes you out to play today?"

"Hmm... I made a promise with Hanabi-neechan today that we'd learn to draw together."

"I see."

The phone suddenly rang. Uesugi Kai picked up the phone, glanced at the name on the screen, and then said to Ai, who was sitting on the sofa watching TV:

"I'm going outside to answer a phone call."

"Okay~"

Kai Uesugi walked from the living room to the balcony, and as soon as he pressed the call button, Yuzuki Hanamaru's voice came from the phone:

"Open the door quickly, I'm at your door."

"..."

There was a moment of silence.

Why didn't my uncle ring the doorbell?

"It's a very simple principle."

"what?"

Your doorbell is broken.

......

Kai Uesugi opened the door at the entrance and welcomed his younger, more fashionable uncle into the house.

Hanamaru Yuuki looked left and right, finally fixing his gaze on Uesugi Kai:

"Xiao Kai, congratulations! You're going to be the champion!"

"uncertain."

"Hey, as long as you win against your fellow disciple and that master of the Shinto school, the championship will be yours soon, right? You've already made it to the semi-finals. All four contestants must know each other inside and out. In my opinion, you still need to be careful."

Hanamaru Yuzuki went into the inner room.

When Hanabi Hanabi noticed her uncle had arrived, she brought him some snacks to treat him.

"Don't you have any alcohol at home? Beer will do."

Hanamaru Hanabi shook her head.

Hanamaru Yuuki looked at Uesugi Kai, his eyebrows furrowed behind his sunglasses: "How can a man not drink?"

"I'm not even twenty yet."

"Hey, rules are rules, but who hasn't secretly had a few drinks when they were young? Have you ever heard the saying, 'It's better to lead your boss in doing something bad than to do something good for him.' Only by doing something bad together will you make that person remember you. Of course, it doesn't have to be a crime."

"It's because of the fireworks that they won't let me drink."

Hanamaru Yuzuki froze for a moment, then looked at Hanamaru Hanabi and said to him, "Well... alright! A man should listen to his wife, especially since Hanabi is my little niece! You should cherish her."

"Yes, that's right, you should listen to my little niece and not drink! What's the point of men drinking? It only makes things worse."

Uesugi Kai noticed that Hanamaru Yuzuki hadn't gotten to the point for a while, and had only been chatting idly.

"Is Uncle here as a guest today?"

"What, you're not welcome?" Hanamaru Yuzuki casually picked up a snack from the coffee table and ate it.

That's not what I meant.

Kai Uesugi still remembers this house; it was his uncle who helped him find it.

He also helped me with my visa when I went to the UK last time.

Although Japan offers visa-free entry to the UK, Uesugi Kai wasn't sure if he could bring Hanabi back, so he asked him to help him get a long-term visa.

After eating some toast made by Hanabi and drinking some coffee, Hanamaru Yuzuki said:

"Didn't you recently want custody of your two little girls?"

"Your uncle... entrusted it to you, little uncle?" Uesugi Kai hadn't realized he was talking about serious business.

"Of course, well, what can I do? I'm not as busy as him. He's a high-ranking police superintendent, a staff officer of the Metropolitan Police Department, and the chief of the Shinjuku Police Station. He has countless cases to handle every day."

Hanamaru Yuzuki sighed.

"But back in the day, I was quite skilled at police academy, even being exceptionally admitted to the First Investigation Division early. That year, life was full of romance and beauty..."

"..."

Kai Uesugi did not interrupt him.

"Until... um... never mind, let's get back to the point and talk about your two little girls."

"In general, if you want custody of both of them, no problem. First, you need their consent, and then place the custody under your sister-in-law and second brother's names. The chances of winning the case are high, but once their biological mother has a proper job, a stable income, and the will to do so, the judge will be more inclined to favor their current guardians."

Hanamaru Yuzuki pulled a photo out of her pocket and pointed to the woman in the picture above, then continued speaking.

"Iwashita Sumiko frequents Kabukicho. From what I know, she doesn't have a regular job right now, but she's been in contact with someone lately."

Hanamaru Yuzuki pulled out another photo, this time of one of a middle-aged man with a stern face.

"Muramatsu Sankisai."

Kai Uesugi glanced at it, but didn't recognize it.

"This person is a subordinate of the Kitagawa Association, and he and the current group leader of the Kitagawa Association, Kitagawa Sakaki, consider each other brothers. He is nominally the group leader's younger brother, but in reality, it is an honorary position. You can think of it as a position with no real power but a high status."

"Something like a retirement home?" Uesugi Kai asked.

"That's roughly the explanation. Our informant in the police force found out that this guy recently lost a lot of money in business and is now very angry. He then suddenly sent one of his own henchmen to contact Iwashita Sumiko."

"Do you think there's anything suspicious about contacting Sumiko Iwashita, a young woman with no income?"

"I lost a lot of money, I was very angry, and then I came into contact with Sumiko Iwashita... um..."

Kai Uesugi looked at the guy in the photo, thought for a moment, and then replied:

"...This means that Iwashita Sumiko possesses something he desires..."

"What exactly is it?" Hanamaru Yuzuki asked with a smile.

"...Aiyi and Qian Aiyi? But they are just two elementary school students."

"The key point is not age, but identity."

"identity..."

Uesugi Kai thought about it again, considering Ai and Chii's identities...

Then there's only one possibility.

It stems from their biological father.

Hanamaru Yuzuki continued to ask Uesugi Kai, "Kai, do you know who their father is?"

Kai Uesugi nodded.

"who is it?"

"Ohara Hisaku."

"Kyusaku Ohara?" Yuzuki Hanamaru clearly had no recollection of this name.

"He runs a securities company in the port area. The company is called Ohara Securities."

Hanamaru Yuzuki pondered for a moment, then said, "I see..."

Soon after, Hanamaru Yuzuki seemed to have figured something out and quickly put away the photos on the coffee table.

"Xiao Chao, don't worry, we'll take care of the guardianship."
