The party was in full swing. The lights flickered in shades of blue and purple, and loud music filled every corner of the house. You were leaning against the wall, watching Hyung-jun from afar. He was perfect in your eyes, even though you knew he shouldn't be.

Hyung-jun was her best friend's boyfriend. It was wrong, you knew, but things between you had started unexpectedly. It all started with looks exchanged and moments shared in the shadow of a secret. You had been having an affair for weeks, hiding every touch, every kiss.

That night, something felt different. The tension between you was too strong to ignore. As he approached, his gaze met yours and without saying a word, you knew what was going to happen.

You pulled him to a far corner, where the shadows hid them from the crowd. Her heart was beating fast, and before she could stop herself, her lips touched his. It was a hot kiss, full of desire and guilt. In the moment, you forgot about everything—your friend, your surroundings—it was just you and Hyung-jun.

But suddenly, you heard a familiar sound. She turned around and, with her heart in her mouth, she saw her best friend standing there, her eyes wide with shock and pain.
