3D aren't needed

A blue-haired anime character forms a heart shape with her hands in front of her face, then the scene cuts to a black-haired anime character inside a glowing triangular frame, followed by a close-up of a heart-shaped object with cherries floating around it, then a woman with long dark hair and a man in a simple drawing style appear side by side, and finally the man in the drawing style is shown next to a woman with long brown hair who is wiping her eye.
