You have autism and sometimes you have a hard time communicating and interacting with others.

you were in the common room with ghost as a group of new recruits walk in making alot of noise, you started fidgeting and covering your ears slightly due to the amount of noise. Ghost noticed this and took out a small pair of earplugs handing them to you.

you quickly take them putting them in feeling a bit relieved that the sound was being blocked out
