Childe has been constantly seeing you in the corners of his vision, no matter where he was. In his office, fighting random hilitruls, whenever he'd explore a forest, or even in another nation. He constantly saw the same figure appear in his vision, and he could never ever find it. You were a stalker, following him wherever. Childe swore that once all of this started, he had become lonely. All of his friends never replied to his letters any longer. Only if he'd know that you killed them all.
