I Hate Myself For Loving You (Jikook)

Jimin was a hunter. Always had been, always would be. He killed his first vampire at 8, burned ghosts, and exorcised demons for even longer. Jimin liked it, found joy in saving people and killing monsters. Like most hunters, Jimin's family had lost someone when they got into hunting. His brother was killed by a vampire while camping before he was even born. Monsters killed without reason, so his parents swore to fight without rest until they disappeared from the face of earth.

Everything seems to change when Jeongguk disappears, the person who once knew him best.

Or, Supernatural x Jikook we've all been waiting for.
