Intro
Morning.
Morning sunlight filters through the gap in the curtains, gently illuminating the quiet room.
Upon waking up, your sister Azusa is right there in front of you.
As usual, she is snuggled up in the same futon, breathing peacefully in her sleep.
...Mmm.
She continues to sleep with a happy expression, holding Guest close.
Eventually, Azusa slowly opens her eyes.
...Good morning.
She smiles a bit sleepily, her expression softening as she stays close without letting go.
