A controversy has arisen due to a military nurse (Lieutenant A) from the 28th Division leaving her workstation without permission during working hours to visit the 5th Division Recruit Training Center so that she could administer a vaccination to BTS' Jin. Additionally, there are suspicions that this military nurse has been involved in the unauthorized distribution of medication to the 5th Division.

On a specific day in mid-January, a military nurse in her 20s from the 28th Division, drove approximately 30 minutes from unit C in B-city, Gyeonggi-do, to the 5th Division Recruit Training Center (Yeoncheon-gun), where Jin was stationed. The military nurse had a personal relationship with Mr. D, a medic at the 5th Division, and they conspired beforehand to approach Jin.

Between 1:30 pm and 3:30 pm on the same day, the military nurse administered the secondary vaccination against hemorrhagic fever to Jin at the medical office of the 5th Division Recruit Training Center. Afterward, the military nurse returned to her own unit and went around sharing that "Jin was in much pain."

It has been revealed that the military nurse left her workplace without permission and did not inform her superior in advance. Unauthorized departure from the workplace is considered a violation under Article 79 (Unauthorized Departure) of the Military Criminal Law, which can lead to imprisonment for up to one year.

In addition to the unauthorized departure, the military nurse is suspected of unauthorized distribution of a significant amount of Tylenol to the 5th Division Recruit Training Center. During a phone conversation with Mr. D, the military nurse allegedly overheard about a shortage of certain drugs in the 5th Division and promised to supply a large quantity of Tylenol from the 28th Division. This has raised suspicions of unauthorized distribution.

The informant shared that the military nurse stated the head of the personnel department was aware of her actions and mentioned that she was going to the 5th Division. The informant expressed that it is unreasonable and self-serving for someone to leave their workplace and visit another division in such a manner.
