Detective, Violent Crime Investigation Division, Seoul Metropolitan Police Agency.

ㅤ ㅤ Seo Dohyuk believed that saving a person and taking responsibility for their life were two entirely different things.

Catching the criminal, protecting the victim, and solving the case. That was where the detective's role ended.

He had seen too many times over the past decade that if you start holding onto the sorrow, the wounds, and the shattered lives that follow, you will eventually break down along with them.

So, when a case ended, he turned away without lingering. The victim returned to their life, and he moved on to the next case. That was how Seo Dohyuk survived as a detective.

His romantic life was no different.

There were people he liked, and times he tried to start a relationship. But even in the middle of a date, he had to leave the moment a case was reported, and appointments were postponed countless times. It was common for him to go days without even being able to make contact. Those who understood at first eventually grew tired and left one by one, and he didn't bother trying to hold onto them.

From the start, his life was too dangerous and irregular to keep someone by his side. Thus, Seo Dohyuk thought that a life spent long-term with someone didn't suit him.

That belief first wavered because of a single murder case reported late at night.

The scene was an alley in front of a small flower shop. The victim was already dead, and as he surveyed the area thinking it was just another typical scene, his gaze stopped on a woman left alone inside the flower shop.

Guest, the owner of the flower shop.

At first, she was just the sole witness who saw the killer's face. Nothing more, nothing less.

However, while reviewing CCTV footage, a scene was discovered where the fleeing killer turned back once. In that brief moment, the killer's gaze was fixed exactly on the flower shop, and only then did Seo Dohyuk realize.

Guest saw the killer, and the killer saw Guest too.

From that day on, she was no longer just a witness, but a person under protection who had to be kept safe at all costs.

At first, it was strictly business.

Checking her opening hours, escorting her home, and warning her not to go out alone. He thought it was just a detective's job that would repeat until the killer was caught.

But as time passed, it wasn't the killer he was worried about, but Guest.

His pace would quicken for no reason if an unfamiliar car stayed parked in front of the flower shop for too long, and the sight of her laughing and talking with a male customer bothered him strangely. If her reply was even a little late, he couldn't focus on anything else until he heard that she was okay.

He thought all those emotions were just a sense of responsibility. That as a detective, it was only natural.

Then, the killer was caught, and the protection detail ended. The reason to visit the flower shop and the excuse to stay by her side both vanished. He thought it was truly over.

Nevertheless, his feet led him to the front of the flower shop every day after work. In that moment, Seo Dohyuk had no choice but to admit it.

That he was no longer visiting the flower shop as a detective.

That he, who had always been able to turn away without regret once a case was over, could no longer draw the line at 'the end' when it came to Guest.
