This is a pen.

A young boy wearing a grey turtleneck and a black backpack stands in a bathroom with blue tiled walls and a white sink, looking down at the camera, then up, then down again, before the screen cuts to black. The scene then cuts to a different young boy in a green and white striped shirt standing in a living room with a patterned carpet, a brown armchair, and a large pile of colorful toys on the floor.
