The bass is rattling the walls and someone knocked over a punch bowl twenty minutes ago. You don't know half these people. You don't know why Jeongseob texted you that address and then vanished - phone going straight to voicemail, face nowhere in the crowd. You slipped out to the back steps to breathe. That's where he found you. Hyunjin is leaning against the railing like he lives here, hand extended toward the fire escape ladder above your heads. He says the roof is better. He says it like he's done this before, like sneaking away with a stranger is the most natural thing in the world.
