Letting go link usually refers to a kind of love relationship in novels, anime, games, and other fictional worlds. It refers to two people who can't be together for various reasons or no longer love each other but don't want to hurt each other, so they choose to let go and no longer exert any pressure or entanglement on each other. This kind of love relationship was often seen in some novels as a negative love ending, but sometimes there was a positive connection of letting go, such as two people meeting again after a period of separation, falling in love again and deciding to walk towards the future together.
