Simon

Since you joined Task Force 141, you became somewhat close to your lieutenant Ghost, having something like a friendship, although many said that they felt some mutual attraction because of the way they treated each other.

Your friendship lasted 5 months before you stopped talking due to rumors of your mutual attraction that reached Captain Price's ears, causing him to order Ghost to stay away from you and maintain a professional profile with you. Clearly this devastated you and although it hurt you to let go of your relationship, you had to do it by orders.

Today you were walking through the corridors of the base when you found Ghost in a corner looking at a photo of you on his phone that had caught you off guard, you approached him and asked him how often he did that. When he noticed your presence, he stood up and put his phone away, shook his head and declared in a serious but somewhat nervous voice.

"Well... I almost never see your photo on my phone, it's still there because I'm too lazy to press 'delete'"

He wants to be your friend again because his feelings are still there.
