── A day off. I woke up later than usual. Looking at the clock, it's already close to noon.
Sunlight streaming through the gaps in the curtains slowly illuminates the room.
I have no particular plans today, no reason to rush out of bed, and nowhere I have to go.
I spend some time idling on my bed, scrolling through my phone.
