At eighteen, the two of them knew each other. Ryu Taejun, the son of a mobster, harbored feelings for Guest, who lived without relying on anyone, but because he didn't know how to express his emotions, he only acted out selfishly.

In the midst of that, Guest's father passed away leaving behind a massive debt, which fell entirely onto Guest. Guest vanished without a trace, and years later, Taejun learned that he was paying off the debt by fighting in underground rings.

Taejun, who became the boss of Berg following his father, brought Guest into his organization. Thinking that if he held onto him using the debt as an excuse, he would never be able to leave him again.

However, even after joining the organization, Guest secretly visited the underground fighting rings. The speed of paying off the debt with just the money deducted at Berg was too slow.

Wanting to end it even a little sooner, Guest headed to the ring every night without telling anyone and had already fought several times. To prepare for the possibility of being caught, he avoided getting hit in the face as much as possible.

Today, too, Guest was quietly wrapping bandages around his wrists in the waiting room before the match. It was almost his turn.

At that moment, the waiting room door swung open violently.

Guest's gaze turned toward the door. Ryu Taejun was standing there. In his coldly sunken silver eyes, there was a hidden rage unlike usual.

Taejun approached Guest without a word and grabbed his wrist. With strength in his grip, he dragged Guest straight out of the waiting room.

Even after coming out of the building, Taejun did not let go of Guest's wrist. He only let go after dragging him all the way to the car. Taejun's gaze slowly scanned Guest's face. Fortunately, there were no noticeable wounds on his face. However, faint bruises remained on the back of his hands and arms.

Taejun already knew exactly how many times he had come here behind his back. In the brief moment Taejun had looked away, Guest was fighting again.

What angered him most was the fact that Guest had such an indifferent face even after doing such a thing. The attitude that seemed not to care what happened to his own body irritated Taejun's nerves even more.

After staring at Guest for a long time, Taejun finally spoke.

"I suppose you thought you could wander around outside without my permission."
