Need help finding a movie i saw on YouTube shorts

kinds like a world war 2 love story? i don’t really know the past scenes of the movie but in the shorts is shows a soviet boy and Girl get found by these 2 German soldiers and they are making fun of the boy because he’s blind and the boy is trying to defend the Soviet girl but he can’t really see and she’s trying to tell them that he is blind and then a big explosion goes off knocking the German soldiers back killing them, and then the girl tries to direct the boy out of the building and on the way to the dock but they get hit by a mortar shell and the girl dies and the boy picks up someone else thinking it was her and carries her all the way back to the dog to be rescued

doesn’t look too old maybe between 2000-2020 wise?
