“There’s nothing unusual.”

The doctor, who examined Mrs. Bang Mi-hee for a long two hours, presented the test results, stating that there was no memory recall.

At first, Exchange took her to the police station to report the crime, but the grandmother, who was certain it was Jae-ik, did not say a word.

So, he brought her to the hospital, and there was nothing wrong.

“How can we help her recover her memory?”

Now that Kang Jae-ik has destroyed all evidence, the grandmother’s testimony is essential.

“Well, Grandma is happiest in this state, so she stops here.”

“……!”

“However, trying to forcibly retrieve painful memories can have a negative impact on the patient. It might be frustrating, but it’s better to observe slowly, considering the patient….”

“Well, I see.”

As the doctor spoke so earnestly, Exchange couldn’t say anything more and politely said goodbye and got up.

“I’m sorry to bother you when you’re busy.”

“No, not at all. I was worried last time because you couldn’t come.”

Oh, right. The doctor who was seeing Exchange seemed to have forgotten and mentioned.

“Someone came then……”

Exchange’s eyebrows, which were turned back, wrinkled slowly.

“Someone came?”

“Yes. When you canceled the appointment. Mrs. Bong knew her well since she was young, and she thought you were hospitalized, so she happened to think of it and came. So, she’s not hospitalized, but she’s receiving outpatient treatment. Today, she said she canceled, and she was curious about Mrs. Bong’s car for various reasons. Even if you ask who it is, she says she’s like a mother because Mrs. Bong took good care of her when she was young.”

Exchange looked at the doctor with a stern face.

“She said someone came when I couldn’t come to the hospital?”

Was it Kang Jae-ik after all?

After the divorce, to be prepared for any potential danger, he personally brought his grandmother to the hospital. It was as if he had been waiting for the opportunity for himself to fall.

‘I want to know the records of the investigation into my deceased father’s case. He had a traffic accident and passed away 8 years ago, and I’m worried that he might have been framed.’

The words of Prosecutor Lee Sung-min flashed in Exchange’s mind.

It’s just a hypothesis, but it wouldn’t be difficult for Jae-ik, who came from the prosecution, to manipulate the accident and buy a junior prosecutor, turning an innocent person into a perpetrator.

[Dash]Mr. CEO. This is Nam Joon-seok. Is it okay to talk now?

As they set off for Seoul with their grandmother in the car, a call came in the car.

“Did you check?”

[Dash]Yes. Prosecutor Lee Sung-min from the Seoul Central District Prosecutor’s Office. He mentioned meeting Ms. Bong last fall through the introduction of Announcer Kang Hanna.

“What’s the relationship with Kang Hanna?”
[Dash]I asked around, and it seems that it’s not mutual. Prosecutor Lee Sung-min seems to have a one-sided crush. Kang Hanna seems to be aware of it and is trying to take advantage. He is rumored to be good at handling situations in the prosecution, and there’s talk about his strong desire for social advancement.

“I see.”

Even though she knows he likes her, she introduced him to Mrs. Bong.

He was making a fuss.

[Dash]By the way, there was a disturbance in President Kang Jae-ik’s office today.

As Exchange was about to hang up, he withdrew his finger from the handle’s control button.

“A disturbance?”

[Dash]Yes. Some thug came and caused a commotion, but what’s suspicious is that President Kang Jae-ik sent out his secretary saying he would call the police.

“So what?”

[Dash]After finishing the conversation, he walked out calmly, whistling. So, I checked the CCTV to confirm his appearance.

“……!”

[Dash]It seems to be him.

Holding the handle with twitching eyebrows, Exchange pulled over and stopped the car on the side of the road.

Hwang Tae-sung. He was a suspect wanted by the police for pushing the grandmother down the stairs on the fourth floor.

Exchange, who couldn’t remember anything at that time, solved the puzzle that Kang Jae-ik had broken one by one, using the notes left in the notebook like a mosaic.

Hwang Tae-sung was a field agent who was periodically tracking the movements of the grandmother, who had requested an investigation. Exchange suspected that he was involved in the crime under Kang Jae-ik’s instructions.

Starting from the traffic accident of his grandfather and father 28 years ago, perhaps even his wife’s accident…!

[Dash]What should we do? I’ve already tracked him, but should I meet him?

“No, keep watching.”

Rather than approaching clumsily and letting him escape, it was a golden opportunity to catch him on the spot.

Now that Kang Jae-ik has already destroyed the evidence of past crimes, it would be better to wait until he commits a new crime and then secure the evidence.

“Contact Prosecutor Lee Sung-min directly. As soon as possible…!”

Since Kang Jae-ik might use him again to do something, he had to hurry.

“And, I wish you could come now.”
