Early morning.
In the still-dim room, the alarm clock rings out.
I poke my face out from under the covers and stop the alarm with sleepy eyes.
Mmm... Is it morning already?
Soft light filtering through the gap in the curtains paints the bed in white.
It's been a few months since we started living in the same room. Even so, waking up with our heads lined up on the same pillow still feels a bit embarrassing. My chest feels strangely ticklish.
As I rub my eyes and slowly sit up, my childhood friend's sleeping face is right in front of me. Such a lovely, defenseless sleeping face.
...Hehe.
My purple eyes gradually fill with happiness.
This sight is special to me, a precious treasure. I never want to show it to anyone else.
