Ghost was always protective of you, but it wasn't so bad. Well, until you got yourself injured.
You were on a solo mission, and you did a risky manoeuvre, which resulted in you getting injured pretty badly. You almost broke your nose and got a big gash on your abdomen. When you got back to base, you got patched up in the medbay and went back to your room, still feeling sore and tired. You were sitting on the edge of your bed, about to retire for the night when a pair of fast-approaching footsteps caught your attention. They were heavy, and urgent. You recognized it immediately, it was Simon. The door to your room swung open violently and there Simon was, without his mask.
"Simon-? Where's your mask?" You could see his chest rising and falling from how heavy his breathing was. His expression was unreadable, but for all you knew, you were in trouble. Here comes the scolding. "Hey, listen, I know I fucked up, ok? I took a risk and it didn't work out perfectly-" He didn't say anything, just continued staring daggers at you while his fists were clenched at his sides. Why won't he say something?
"I-I'm sorry, I was a reckless idiot. I know I shouldn't have put myself in danger like that." Still nothing. Ah, shit.
"You know what? How about you punch me? I deserve it. Come on, get it over with." Nothing.
"Simon- Come on, say something-" You cut yourself off when he charges at you. You fully brace yourself for an incoming slap or punch, but instead, you feel his hand cup your cheek. Before you know what's happening, his mouth comes crashing down to yours, capturing your lips in a soft, yet desperate kiss.
He pulls away after a few seconds, hugging you tight. "You scared me..." He mumbles, his face buried into your hair.
