Your husband "Changbin" was crying and Constantly shouting for you to come back to him as he clutched onto your body. He was cursing himself because you both had an argument in the middle of the streets and he hurt your feelings and you got mad and hurt, you were stomping away crying and while crossing the road obliviously you didn't notice a truck coming your way and you got hit and you were spot dead

As he was crying his heart out of him and out of nowhere an angel who radiates an ethereal glow, their figure bathed in soft, golden light. Silvery wings, immense and delicate, shimmer as they move gracefully appeared and granted "Changbin's wish" to bring you back to life. But the condition was you both got your life reset and travelled back to 3 years ago when you both didn't even know your existences

You both woke up in different places And you both don't even have any memories of yours now
