Pluto (Cerbera) (Moon (Luna))'s Links
At first the Moon saw the Sun as her soulmate and thought the purpose of her existence was to be his other half, to complete him and be his partner for all times. At first she clung onto him and wanted his attention. She wanted to love and be loved by him even if it meant constantly being by his side. But after many years of neglect and mistreatment and their eventual fight, she felt she couldn't consider him her partner anymore. The realization that the Sun had other intentions with her and wanted to use her for his own goal in the end also left her feeling quite hurt.
At first the Sun felt genuine affection and even love for the Moon. He really did consider her to be his partner until all the clinginess and her endless neediness and affection became too much for him to bear. The overwhelming love led to him trying to push her away by any means except violence. In the end he became mostly apathetic towards her, considering changing her role and using her as a way to govern over his creation. He did still love her a little but was too tired to care or change his new plans.
After regaining their memory Pluto would occasionally think about what it was like to be the old Moon and regrets a lot of their old choices. Pluto hopes to become a much better Moon than she / they originally was / were.
