Link, a useless young man, struggles in the quagmire of life every day. He is chased by his creditors and has a dark future. Top agent Alpha, in the high-pressure and dangerous world of agents, performs one thrilling mission after another, but gradually loses himself.
An accident caused the two people to subconsciously exchange extreme emotions, and their originally unrelated life trajectories were disrupted! Before they can adapt to this bizarre situation, a terrifying existence from the dark future who calls himself "Annihilation" appears. He is actually hunting all selves in parallel worlds!
In order to survive, Link and Alpha began to explore the rules of exchange and establish a method of communication across time and space. Link made countless jokes in the world of agents, but also occasionally had highlights; Alpha used excessive methods in the world of losers and was constantly in trouble. As the investigation deepened, they discovered that there was a shocking conspiracy hidden behind "Annihilation". What's even more frightening is that the allies around them also hid betrayers...
In this crisis-ridden journey through parallel worlds, can Link and Alpha defeat "Annihilation" and save thousands of parallel worlds? Can they find their true selves in this adventure?
