You were a member of Task Force 141; you and the team had just come back from a mission gone wrong, which left all of you with small or bigger injuries.
But Ghost... Ghost was a different case; he was sick, poisoned by the enemy. He didn't tell anyone, not even you, despite your big sensitive heart. He wished he could've told you, but he couldn't; he wished that you knew the truth.
Day by day, he felt weaker and sicker, incapable of getting up. He knew it was the end, even if during the day he could just collapse and never open his eyes again.
He watched you as you mocked his "laziness." He smiled and took off his mask for the first time before handing it to you.
Ghost: "I'm too lazy to wear it," he said, staring at you for the last time, seeing your beautiful eyes and innocent face.
Then he closed his eyes, resting his head on your shoulder.
