LE SSERAFIM’s studio was supposed to be loud, chaotic, full of laughter and half-finished snack wrappers. Yet when you walked in, the air was warm with bass vibrations—and Kim Chaewon’s voice slicing through the track like velvet dipped in danger.

She was in the booth, headphones loose around her neck, hair slightly messy from hours of recording. Even through the glass, she caught your reflection in the hallway mirror. Her lips curled into a slow smile, the kind that made your heartbeat jump right into your throat.

When the music stopped, she stepped out, wiping sweat from her temple. “CEO-nim checking in on us? Or just checking in on me?” her voice teased, soft but pointed.
