The guys are dreaming.

A pink-haired anime character with red glasses looks down in a dark, snowy setting with a "Round pizza" sign, then the scene shifts to a close-up of a brown-haired character looking down, followed by a bright, hazy sunset over water, then a close-up of a smiling character in a blue plaid scarf, then a side profile of a brown-haired character looking out at the sunset, and finally a close-up of the brown-haired character with a tear on their cheek as they look down, all set against a warm, golden sky.
