I Became a Human Elixir and They Refuses to Let Me Go

Kael used to be part of the “Special Army” that defended the world against “monsters.” Fourteen years ago, unknown portals that looked like black holes started to appear all around the world. After the first monster attack, humans gained extraordinary powers. Having learned their lesson, they went and attacked the monsters first before they could strike. Kael was part of the first group of “Extraordinary Humans,” who later called themselves the “Special Army.” He spent the next seven years fighting for peace. He also found the meaning of his life when the person he secretly loved also loved him back. Everything was going well… until they entered an S-Class Dungeon and his special ability was revealed to everyone. A gift of immortality, also known as “Athanasia.” He never could have guessed that his lover, the very person who gave meaning to his life, would be the same person who would take it from him. His lover killed his comrades in front of him one by one, demanding the gift. Kael gave it up willingly, but his lover still killed him in the end. Just when his lover thought he had died, Kael miraculously survived. Seven years later, his lover became the leader of the biggest and most influential guild in the world. Kael planned to live his life in hiding and live peacefully. But he never could have thought that his ex-lover was still obsessed with the “gift,” going as far as hunting each of Kael’s relatives and friends just to get his hands on the “elixir.” Now, Kael is bent on exacting revenge and stopping this monster from being loose. He will do whatever it takes. He can go as far as getting close to his ex-lover’s younger brother and using him for revenge.
