A close-up of a red, glowing eye with a black pupil transitions to a red-tinted scene of two characters embracing, followed by a character with black hair and a red eye standing against a red, energy-filled background, then a character with white hair and a red eye, with the text "Bubble_cat" overlaid, which then shatters into red fragments, ending with a red and white striped object against a black background.
