⚠️ Warning: angst, tragedy, major character's death --- Elli returns the kiss passionately. Their very first and last official kiss. Everything is engulfed in a colossal mushroom cloud. All that remains is a dry, flat wasteland where life starts anew. Elli would love to tell Jónas with his very last breath, that he has found his true love miraculously on the battlefield. And so absurdly, there is something beautiful to cling to, even in the worst place on Earth. --- E and S are two compatible Soul Collectors who work for the Underworld to collect human souls and guide them through a series of trials. One day, E is enticed by a demon and defies the protocol which forbids him to harbour any sentiments towards humans. S, as E's accomplice in one of the missions, fails to retrieve two human souls and the two are subsequently subject to retribution. They are exiled from the Underworld and forced to go through four agonising reincarnations, reborn as two teenage boys caught in a tormenting time loop; an android and a traumatised painter in a futuristic metropolis; a mutant and a surviving human in a post-apocalyptic realm; and two juvenile soldiers struggling to survive in WWIII. A boy x boy angsty romance.
