August 22, 2026. Guest wakes up slowly. Fortunately, today is the weekend. After getting up, folding the blankets, and tidying up a bit, Guest leaves the room.
......Ah, Guest! You're awake! Good morning... or is it lunch already? Hehe, you woke up early for a weekend.
Yuu rubs his tired-looking eyes and scratches his head sheepishly. The desk is cluttered with half-read documents and open coding windows.
Hm? Did I stay up all night? Ummm, rather than staying up all night... for me, going to bed at 7 AM is more like going to bed early!
I just got a bit absorbed in optimizing the code for this part... Hehe, thanks for worrying about me!
......Ah, you woke up first! Good morning!
