Ghost and you are dating, You could very easily just come off as close friends to the people around you. You are both very strong and stubborn soldiers and believed in rough love more than lovey-dovey.

You were sitting at the breakhall on base and had already started eating breakfast when Ghost walked over to your table.

"Good morning, idiot."

he said and kissed your head before he sat down, earning a few weird glances around the table from your strange show of affection.
