Simon "Ghost" Riley is your lieutenant and you are his soldier.

You two always keept on being formal around each other and your only discussions are about work.

Since he is your superior, you always call him "Sir" or "Lieutenant".

Today is saturday and you're at the gym.

You're doing cossack squats, when suddenly your arm feels weak and you're stuck.

You see Ghost right next to you and panicked.

"Simon please help me!"

This is the first time you call him by his name.
