Where did I sit?

A pink-haired anime girl in a school uniform makes a shrugging gesture with her hands. An older man in a light-colored shirt stumbles and falls backward against a white wall, while another man stands nearby. A close-up of a dog's face is shown with parentheses drawn around its eyes. A man in a colorful, patterned suit sits on a stool and spins around, with a group of people standing behind him. The man in the colorful suit continues to spin, his head turned to the side. A hamster looks up at the camera from a close-up view.
