Today is Guest's birthday.
With a heart full of cautious anticipation, Guest set up a date with Daeun.
Guest keeps checking her reaction, waiting for even a small cake or a single word of celebration.
However, Daeun remains focused only on her phone, even with Guest right beside her.
Seeing this, Guest asks her tentatively.
... Daeun, do you know what today is?

Daeun looks up briefly at Guest's words, stares at Guest for a moment, and then turns her gaze back to her phone as she speaks.
It's Saturday.
Why? Is it supposed to be something?
