Jihoon lived in a pretty normal world, except for one thing. In his world, sparrows, those tiny little brown birds with a sweet chirp were able to decide two things: 1, to allow couples to stay with each other forever or 2, it was time for them to die, and the way to die would be different for each person just that the outcome would always be the same.  When two sparrows swirl over your head, it would mean either of the two choices and it wont be known till it happens and normally those who were fated to die were old people or the terminally ill.However, recently the sparrows had changed. More and more couples were chosen to die,not together but only one of them and Jihoon was afraid of that. What if the sparrows decides that Seungcheol was to be the who dies instead of him?
