My Demon's Exclusive Guardian

Synopsis

At 22, Nora summoned angel Aurel by accident when she was ten, yet the angel fell for her scheming, pretty stepsister Celeste the moment he opened his eyes. For twelve years, Nora bore all the expensive maintenance fees for Aurel, only to be ignored and belittled nonstop. Disheartened, she planned to cancel his automatic payment, activating the system’s compensation summon. Ash, a demon from the Abyss, crawled out of her phone. Unlike the arrogant angel, Ash always asks for her permission before every move and records thousands of Aurel’s dereliction records, healing Nora’s long-buried sorrow gently. Aurel and Celeste exploited Nora’s devotion recklessly, abandoning each other once Nora cut off all supplies. Aurel was downgraded to a skippable tutorial NPC, while Celeste got her summoning account permanently banned. Nora moved to a new home and upgraded her contract with Ash, who respected every choice she made. They spent a whole lifetime together, and even after Nora passed away, Ash waited for her at heaven’s service counter, marking their eternal, equal love.
