I GOT IT!

In a brightly colored kitchen, a pink-haired girl stands at a counter while a boy in a blue outfit approaches her from behind, reaches out to touch her shoulder, and then walks away, leaving her to turn and look at him as he exits the frame. The scene then cuts to a view from inside the kitchen looking out a window at a large, fantastical landscape filled with purple, mushroom-like structures under a twilight sky.
