Trending clip of an anime character from like 2020-2022

im trying to find this clip again but i forgot its name, i remember there was a trend on tiktok around the 2020-2022 era and it was a clip of an anime character turning his head to look at the distance and then when the camera looks at his face again hes (i think it was a boy im not totally sure, it could of been a girl) smiles softly, gives off like a hopeful expression sort of. the animation was really smooth and the visuals were also really pleasing. i think the character had white/light hair and the background/distance he was looking at was like dystopian in a way? he was rather young looking, not a full on child but probably around 15-25. if anyone knows what i mean please lmk ive been trying to look for it for weeks 😭
