I'm in Detective Conan, and I start with the Grand Theft Auto system.

Miwako Sato pulled a police handbook out of her inner pocket.

She opened the manual, turned to the page with the bookmark, then turned the manual around and pushed it in front of Lin Shen.

"President Lin—don't you usually like reading mystery novels? Could you take a look at this for me?" Her tone was expectant.

Lin Shen glanced down at the handwritten words on the manual page—"Sorrowful Boy" (しゅうしろう).

He immediately understood the case of the sorrowful young man.

With a slight sigh, Miwako Sato said, "Eighteen years ago, a policeman was hit by a car while escorting a prisoner."

According to eyewitness accounts, the policeman repeatedly uttered "sorrowful lover" before he died.

"For so many years, no one has known what this code means, which is why the case has remained unsolved for so long."

"President, can you guess... what this 'melancholy lover' means?"

Lin Shen glanced at Sato Miwako, then said, "Let me think about it."

In fact, he had already decided to help Sato Miwako decipher the code.

He couldn't help it; his conscience bothered him!

During this time, Lin Shen had lost count of how many times he had taken Sato Miwako to the hospital.

That unlucky kid... why do you always have to run into me?

After pondering for a moment, Lin Shen finally spoke, "Officer Sato, I have an idea."

Sato Miwako didn't seem to have any expectations. She took a sip of her coffee and asked, "What are your thoughts?"

Lin Shen didn't keep her in suspense and directly told her the meaning of the code: "I think it's not some 'sorrowful lover,' it should mean... 'Confess?' (じしゅしろ)"

"Pfft!!!" Upon hearing this, Sato Miwako spat out the coffee she was about to drink.

Luckily, Lin Shen dodged quickly, otherwise he would have been sprayed in the face!

"I'm so...sorry." Sato Miwako quickly grabbed a tissue to wipe her face, her cheeks flushed red with embarrassment.

"It's alright, it's alright." Lin Shen waved his hand, signaling the other party not to get agitated.

"President Lin!! You...you...how did you think...this is 'confessing'?" Sato Miwako asked excitedly.

She was now absolutely certain that Lin Shen's reasoning was correct!

Lin said shamelessly, "You go first. That policeman was hit by a car and must have been seriously injured. He must have been weak and feeble when he spoke."

"In that situation, it's perfectly normal for passersby to not hear clearly, or even misunderstand!"

"Yeah, right!!" Sato Miwako slapped her own blockhead and said regretfully, "Yes! Why didn't I think of something so simple all these years?"

She was somewhat excited, but mostly thrilled; the weariness in her eyes had vanished, replaced by a gleam of excitement!

She quickly analyzed, "Turn them in... So, my father made the criminal turn himself in back then? That means they must have known each other!"

Miwako Sato was so excited that she forgot to mention the policeman and directly said that he was her father.

Lin Shen pointed to KA·N·O in the handbook and deliberately said, "This should be the friend... KA·NO, does your father know this friend?"

Miwako Sato corrected, "President Hayashi, it should be KA·N·O, you're pronouncing it wrong."

Lin Shen shrugged and said, "Sorry, I'm just used to reading it this way."

Upon hearing those words, Sato Miwako felt as if she had been electrocuted.

She stared at Lin Shen, her whole body trembling, and stammered, "President Lin, I...I...I know who the culprit is!"

"I know who he is!!"

With that, Sato Miwako slammed the police handbook shut and took several sips of coffee to calm her excitement.

She closed her eyes, took several deep breaths to calm her excited emotions, and then said with a beaming smile, "President Lin, I'll definitely treat you to coffee another day!"

Lin Shen waved his hand and smiled, "It's good that I can help, no need to be so polite."

Miwako Sato stood up, ready to leave, but then she paused.

She looked at Lin Shen with a hint of amusement in her eyes and a smile on her lips: "I understand, President Lin."

Lin Shen looked up at her, somewhat puzzled.

Sato Miwako lowered her voice slightly: "You want me to keep this a secret, right? No problem!!"

She winked at him. "I'm not the kind of woman who talks too much. I won't go around telling everyone about your relationship with Xiaolan."

Don't worry!

Lin Shen was stunned for a moment before realizing that Sato Miwako had misunderstood.

She considered helping him decipher the code as a reward for "keeping his secret."

He offered no explanation.

He just smiled, picked up the cup of goji berry water, took a sip, and let her be.

As long as the goal is achieved, that's fine.

She accepted his kindness, so she wouldn't delve any deeper into his past.

Sato Miwako tilted her head back and drank the rest of her coffee in one gulp, then put the cup back on the table, nodded to Lin Shen, and excitedly walked out of the coffee shop.

The wind chimes rang behind her, and after the glass door closed, her figure quickly disappeared into the night.

Lin Shen sat in the booth, watching her hurried figure disappear into the distance outside the window. He had originally wanted to say something to remind her.

Eighteen years have passed since this case, and Shuji Kano isn't an idiot. If you confront him with a verbal testimony that has deciphered the code, you'll most likely be rejected.

But after thinking about it, he finally gave up and swallowed back the words he was about to say.

After all, he really didn't have any other way to legally capture Shuji Kano.

…………

The next afternoon.

When Lin Shen pushed open the glass door of the coffee shop and walked in, Mingmei was wiping cups behind the bar.

When she saw him come in, she put down her cup and walked over, saying, "Mr. Lin, you've finally arrived. Officer Sato came over around noon and has been waiting for you."

Lin Shen looked around the store but didn't see Sato Miwako: "Where is she?"

Akemi put down the cup-wiping cloth and turned to walk towards the lounge: "She's in the lounge. She probably didn't sleep all night, and she fell asleep while waiting, so I told her to go back to the lounge and lie down for a bit... I'll go wake her up now."

After a while, the door to the lounge was pushed open, and Sato Miwako came out rubbing her eyes. Her hair was a little messy, and her coat was wrinkled, clearly showing signs that she had taken a nap on the table.

When she saw Lin Shen, her eyes lit up immediately. She walked over quickly and began to complain in a tone that was a mixture of grievance and confusion: "President Lin, I went to confront Kano Shuji yesterday."

"He pleads not guilty, absolutely not!"

"No matter what I say, he won't admit it. He even asked me to produce evidence, but so many years have passed, what evidence could I possibly have?"

"He destroyed them all... I can't do anything about it now."

Her voice trailed off, filled with a deep sense of helplessness. "I know perfectly well he's the killer, but I just can't bring him to justice. What should I do?"

Lin Shen looked at her face, which was covered in dark circles, and said innocently, "Well... I can't help it."

Upon hearing this, the glimmer of expectation that had just ignited in Sato Miwako's expression quickly faded as if someone had poured cold water on it.

She was greatly disappointed: "What? Even President Lin can't do anything about it?"

Lin Shen leaned against the edge of the bar, arms crossed, his tone tentative: "Couldn't you... sneak in and investigate? Just like in the movies... um, a proper movie."

"First, we'll disguise ourselves and sneak in to find evidence."
