Mobogatari

A blonde anime girl with large yellow eyes and a white dress appears in a close-up, then jumps onto a black-haired boy from behind, wrapping her legs around his waist and hugging him tightly. She is carried by him as he runs forward, then they fall to the ground in a blur of motion, after which she is seen sitting triumphantly on a piano with her arms crossed while the boy lies on the floor. The scene takes place outdoors near a chain-link fence and later transitions to a room with a piano.
