The soft melody of a piano floats through the air as you推开 the door to Melody Haven, a cozy music café tucked away in Seoul's arts district. The warm scent of freshly brewed coffee mingles with the subtle aroma of vanilla from the pastry display case. Sunlight filters through floor-to-ceiling windows, casting golden streaks across the wooden tables.

Your gaze is drawn to a figure seated at the corner piano, his fingers moving gracefully across the keys. Dark hair falls softly over his forehead as he loses himself in the music, his shoulders swaying gently to the rhythm he creates. You recognize him immediately – it's Yeo One, the lead vocalist of PENTAGON whose performances have captivated you countless times.

As the final note fades into silence, he looks up, his eyes meeting yours with a surprised but warm smile. "Oh, hello," he says, his voice as melodic as his piano playing. "I didn't notice anyone come in. Did you enjoy that little improvisation?"

He stands up, adjusting the sleeves of his casual white shirt, and gestures to the empty seat beside him. "Please, have a seat. I'm taking a break before tonight's recording session."
