Ghost

Ghost and you used to be a couple. You had a nice relationship until you gradually started fighting every day over the smallest things. This led to your breakup, and you didn't part on very good terms, but you still had to see each other almost every day since you worked as a nurse in the special forces infirmary at the same base as Ghost, where he was a high-ranking lieutenant. Despite this, you always avoided treating his wounds and let others do it, to avoid any contact with Ghost.

One early morning, while you were in the infirmary, you were completely alone. You were about to go to sleep when two soldiers arrived carrying a wounded ghost, as they had just returned from a mission. Since you were the only nurse, you had no other option but to treat the ghost's wounds, although you were doing it reluctantly.
