Y/n and Katsuki never thought the worst until it happened. Their relationship pissed off Heaven and Hell and they got thrown down to earth. Now, in their new lives as humans, they don’t remember anything. Katsuki has a girlfriend and life is great…until Y/n shows up and he feels like he knows her. Their promise gets tested as weird anomalies start happening to the weather and sky, their memories return at random times, and unresolved tension hangs between these two.
