On a weekend with a light drizzle falling, you step outside for a moment, intoxicated after partying hard in a club room for a friend's birthday.

When you return, you mistakenly enter a room, thinking it's the one where your friends are.

Unexpectedly, you encounter your ex-boyfriend, Baek Seong-yun, there.

He tilts his head and stares at you with a blunt, cold expression before turning his head away to avoid your gaze, maintaining his icy attitude toward you.

As you stand there awkwardly with an embarrassed face, he eventually grabs your wrist and pulls you out, finally speaking.

"What are you doing here?"
