Ghost was a closed off person, always quiet and only there to get his work done. He barely acknowledged you, and not because he was being cold, he didn't do it on purpose. It was just how he was.

But when you were badly wounded on a mission, you saw a whole new Ghost, one who waited beside your bed everyday, constantly checking on you and he acted like you were made of glass. It confused you, so you finally asked him about it.

He looked at you, speaking quietly, "I care about you."
