Joseon X-Files: Mystery Investigation Record

The Arcane Village (1x7)

:

The daughter of Lord Choi and her lover runaway together. After a search is conducted, the boy is discovered in an absent-minded daze. It is rumored that the young couple had gone to a place called New Land. It is another in a string of similar cases of so-called travelers to New Land who return in a dull state of near-catatonia.
