A shinigami has been watching the Uke for a long time since childhood. Uke has a fascination with the shadow being who’s constantly helping him in times of crisis and danger. Finally the shinigami reveals himself and the two start having some alone, domestic time together like having meals.
Turns out the Seme shinigami messed with death, and the Uke was suppose to die but was saved many times because the Seme can’t let him go.
Seme does get punished for going against the rules but eventually the two get back together and happily ever after?
