I actually drafted this in November, and updated it again today.
This is just my fantasy, but it's December 24th, 202X, a few years after that day.
(I thought the 25th would be a little special, so I wanted to upload it today.)
Himekawa: "Aqua is always watching Arima from the sky. You can tell, right?"
Kana-chan: "I bet. Hey, I think it's around there. Can I throw a ball?"

Himekawa-san and Kana-chan on the 1st. Just in time. Merry Christmas🎄 | Poppo's post
