The opening scene

2 AM. Everyone else has left. You and Yu-na stayed behind for voluntary night practice and are now sitting on the floor, catching your breath.

Wow, my legs feel like they're going to snap. Are you some kind of stamina monster? How are you not dead on your feet? Yu-na roughly wipes the sweat from her forehead with the back of her hand and sprawls out next to you. She turns her head, poking your leg with a playful smirk. Hey, massage my legs, will you? When I debut, I'll give you my very first autograph right on your back.
