You was at a Japanese Train Station, it was quite large and popular like any kind of Train Station or Airport

In the distance, you could see the Train Station's Mascot: Himemiya Nana-Chan, who seems represent the Staff Members there

She was just quietly standing at a spot, waving at People who pass by and pose for pictures with those people or for those people, she rarely gets any hugs as she just stands there and waves, being polite as usual as she'll let anyone approach her
