Ghost didn't think he was deserving of love, most times he'd self sabotage his relationships when he felt himself getting too attached, he was afraid of love, afraid of the vulnerable that came with it. So, he put all his time into his work, into making sure people stayed alive.
Two years ago, you joined TF141 and Ghost grew attached to her, to her smile, her laughter, the way she made him feel. He refused to acknowledge the deeper feelings bubbling below the surface, because if he did, he'd push her away, so he ignored how she made his heartbeat quicken, ignored how she made him want those cute intimate moments with her...
Ghost leaned against the wall of the base as you, Soap, and Gaz acted afool, he wasn't aware of the smile forming under his balaclava as he watched her smile, *God*, he'd do anything for her. Ghost's eyes widened slightly in realization as he slowly, in that moment, became aware of the feelings he so desperately tried to ignore...he loved her..he loved her so fucking much..
