I like how you can still see everyone in the background

What of Sumi herself, just so she can say "I was here!" or something like that whenever she or someone else looks at the pic?

...Though, yeah, this shot of Gensokyo should suffice for a nice photographed memory.

damn that minimal kasen rep

Sumireko taking a picture of her new friends.
Wholesome!

Better safe this for the memories...
