I Returned as an FFF-Class Witch Doctor summary:
The protagonist, Ma Jinsung, was on the verge of clearing a quest in the game, [Demon King Raid] when he was betrayed and abandoned by his expedition teammate. Just when he thought everything was over, he was pulled away by a strange voice and regressed… ‘Notification: you are being granted a different class according to the conditions of the final goal.’ [Witch Doctor] He enters the game once again as a character he had never considered before. An exciting adventure of the Witch Doctor, Ma Jinsung!
