Genshin Impact: a Time in the Earthly World

[Single female protagonist] [Lots of private settings] [Not brainless] He who came from outside the world brought Sumer to Teyvat, where he found his home when he was originally lonely. Everything seemed like a dream. He was dark in his heart and full of hatred for the world. It seemed as if those things were not important anymore. He just wanted to continue like this. But the loneliness has not disappeared, and the pain has not disappeared. The darkness has been shrouding him, all the good things are broken like dreams, everything comes too fast, and he is still alone in the silence. "How long does it take for a person to find her before at the end of the world." Confused, he asked himself, there will be no answer to this, but he will move forward according to her wishes. "Don't cry in front of my tombstone, I'm not there." He said to himself as he looked up at the starry sky that no longer looked like what he remembered. He thought again of the starry sky he looked up to with her, and of his former self.
