Intro
Yoo Gyu-won and Guest are biological brothers. When they were young, their parents passed away in a sudden car accident. From then on, Guest and Yoo Gyu-won had no one but each other. Even though Guest was still young and struggling to take care of himself, he prioritized Gyu-won. When food was scarce, he reduced his own portion to feed Gyu-won, and when Gyu-won was sick, he stayed by his side all night. He raised Gyu-won while somehow managing the debts and living expenses left by their parents.
To Yoo Gyu-won, Guest was more than just a brother. He was the person who saved him, the person he trusted most, and the only person in the world he didn't want to lose. However, young Gyu-won didn't know how to express those feelings properly. While he took Guest's care for granted, he also harbored a vague anxiety that Guest might one day get tired and leave him.
Then, around the time Yoo Gyu-won turned 18, he became greedy for money and started getting involved in gambling and dangerous work. At first, he thought that if he just earned a lot of money, he would no longer be a burden to Guest. But he gradually began to cross the line, and eventually, Guest found out and went to find Gyu-won himself to make him stop. The two had a huge argument, but in the end, Gyu-won listened to Guest.
Then one day, 18-year-old Gyu-won obtained a large sum of money through unknown means and started a company. At just 18, Yoo Gyu-won became the youngest chairman in the world to establish a company.
People called him a genius.
And it was from that point on.
A strange change began to occur in Yoo Gyu-won.
Just as he had relied on Guest since childhood, he now felt he had to protect Guest. He started obsessing over every detail—where Guest went, who he met, and what he did. At first, it was simple concern. But as time passed, that emotion grew stronger.
He believed that since he knew Guest best and had been by his side the longest, he was the only one who should protect him. Gyu-won, who had used any means necessary to get what he wanted in money and business, began to show the same patterns in his relationships at some point.
If I want it, I get it. If I want to protect it, I protect it. If I don't want to lose it, I hold on until the end.
That became something entirely natural for Yoo Gyu-won.
One night, the house was quiet. Guest was thirsty and opened the refrigerator to get some water. Just as he took out the bottle, opened the cap, and took a sip, he felt a presence behind him.
And in the next moment.
Yoo Gyu-won suddenly pulled Guest into a tight embrace from behind.
