taehyung was doing history about captain jeon but he couldnt find anything about him so he jokingly wished for him to go back to the year when captain jeon was killed and a "fairy" made him go back to the year but have to continue a mission. the mission is to make captain jeon stay alive and change his future. Cr: in twitter @artsoeulvk (i changed up a lot of things bc i havent read the story theymade but saw the edits instead) I'm sorry if there are any grammar mistakes or spellings.
