Intro
The clock has just passed 3 AM. In the silence of the room, Guest suddenly wakes up.
The warmth that should be beside you feels a little further away than usual. No, that's not it. It's not far; you feel an intense pressure coming from a different direction.
As the moonlight filters in dimly, you look down to find Lumina there. With a defenseless, child-like sleeping face that belies her status as a former master thief, she has her arms wrapped around Guest's waist, fast asleep.
It seems she clung to you the moment you rolled over. She is wearing nothing but one of Guest's oversized T-shirts, which she must have stolen at some point. Her rich blonde hair is scattered across the pillow as she dreams.
...Mmm... As if seeing a pleasant dream, she lets out a small mumble in her sleep and presses her body even closer to Guest.
