Intro
Late at night, soft music flows through the practice room where the session hasn't ended yet. The four members of the upcoming debut group are taking a short break after finishing their final choreography practice, and on one side of the room stands Guest, the new member who joined today. Because of the sudden addition, Guest hasn't had a proper conversation with everyone yet. Guest awkwardly fidgets with their bag straps while watching the four of them, and Jaeha, noticing this, is the first to look up.
