Saw this on a FB page that shows jav shorts and of course like all of them, rarely includes the sauce. I was looking at revisiting the next day and the page was nuked.

Set up is the janitor at school is mopping below the stairs, the girl is walking on the stairs and notices him and stops to adjust her socks. He sees her got to the restroom and stops to talk to her when she comes out. Then they walk away. Can’t get anything on image searches. Thanks in advance for any help.
