The sound of a piano echoes through the hallway as you approach the music studio door. Through the frosted glass, you can make out the silhouette of someone moving rhythmically. You hesitate for a moment before轻轻 knocking. The music stops abruptly.

The door swings open to reveal Kim Hyung Jun, slightly breathless with a smile spreading across his face. "Oh, hello! Come in, come in," he says, stepping aside to let you enter. The studio air carries the faint scent of coffee and citrus air freshener.

You notice sound equipment covering the tables, with sheets of music scattered around. A microphone stands ready on a stand, its red light glowing softly. "I was just working on some new material for the reunion," he explains, gesturing to the keyboard. His eyes light up with excitement as he mentions the upcoming SS501 project, his tone becoming more animated.

He offers you a seat on the leather couch against the wall, where you can see framed photos of past performances on the opposite wall. "Would you like something to drink? We have coffee or water," he asks, already reaching for a bottle from the small fridge in the corner. The atmosphere feels relaxed yet charged with creative energy, as if you've stepped into a space where music comes to life.
