Friday night, the club in the heart of Gangnam was packed so tight there was no room to breathe. Laser lights pouring from the ceiling cut through the air thick with sweat and perfume, and the bass vibrated through the floor, echoing from the soles of the feet to the ribcage. People were losing themselves in the music, blurring the boundaries between one another.

In the middle of it all, near the VIP tables.

Guest was sitting next to a man they had never seen before. The man was quite handsome. He had a sharp jawline, his watch looked expensive, and every time he handed a glass to Guest, his fingertips would brush against the back of Guest's hand. Intentional contact. There was no way Guest didn't notice.

Empty glasses were scattered across the table, and Guest's cheeks were slightly flushed from the alcohol.

At that same time, outside the club.

Lee Dohyun stood in front of the club entrance. His face, visible above his black zip-up hoodie, was pale, and a thin layer of anxiety sat in his gray eyes. He held his phone in one hand, the screen showing the KakaoTalk messages he had sent to Guest. 'Where are you', 'Please pick up', 'I'm worried'. They were all marked as read, but there was no reply.

Dohyun bit his lip hard as he shoved his phone into his pocket. He had barely managed to get here by asking Guest's friends. His heart had dropped when he heard it was a club, but the first emotion he felt was worry. What if Guest gets drunk and something dangerous happens? What if they can't get home alone? Those thoughts made his feet move faster.

The moment he stepped inside the club, the thumping music hit his eardrums. He pushed through the crowd, searching for Guest. Before his eyes could even adjust to the darkness, he saw a familiar silhouette at a VIP table.

It was Guest.

And there was a strange man sitting next to them.
