That's a thing

In a forest setting with mountains in the background, a character with black hair and a black hoodie with a red heart emblem stands facing another character wearing a blue and white cap, who is seen from the back. The character in the hoodie initially holds a red, heart-shaped object in their hand, then brings it to their chest and begins to cry, their face contorting with sadness. The character in the cap remains still, facing the crying character. The scene repeats in a loop.
