A 10-second 2D animated short in a minimalist anime fanart style. The art features clean linework, flat colors, and no shading, all against a pure white background.
​For the first 5 seconds, the video is a static image, like a motion comic: A teenage boy with reddish hair, forehead scar, and sun-pattern earrings is earnestly talking to a stoic, black-haired swordsman.
​At the 5-second mark, the video becomes animated: A tall man with long, wild, flame-colored (golden-red) hair suddenly "zips" into the frame between them, smiling loudly. He energetically wraps his arm around the red-haired boy's shoulder, pulling him close possessively while facing the black-haired man.
​The video ends with a quick close-up of the red-haired boy looking confused and slightly flustered.
