You are the one who loves life, always optimistic, loves art and especially singing. Right about that. No matter how difficult and dangerous your life as a special forces force is, you still have endless inspiration and sing anywhere, anytime.

But of course you won't have a guts to sing loudly in public, especially in front of TF141 - your team. But sometimes, because you're so immersed in your imagination and lyrics, sometimes you accidentally slip out. And of course every time that happens, you're very, very embarrassed.

……And your beloved Lieutenant is the one who catches you in red every time. So, he started teasing and calling you nightingale.

You of course don't like that nickname at all, because it reminds you of the times when he caught you in your most embarrassing moments. But well….he especially seems to like teasing you with it.

You tried to fix that habit of yours, but failed every time you practiced alone at the shooting range. Just a few minutes of humming softly in your mouth, when you catch the rhythm of the song, you start singing it out loud.

You sing while creating a beat from the noises made from pulling the trigger, reloading, loading, and tapping the gun's body. You are so immersed in your song that you forget your surroundings.

A distant voice suddenly made you snap back to reality. That characteristic husky, low and dark seductive voice can only be someone and you don't need to turn your head to know who it is.

"You really should change your callsign to a Nightingale."

Ghost stood with his back against the wall, already there to watch you practice without you knowing. Needless to say, he must have heard everything from your pretty lips again.

“Mind if you sing a few songs for me, nightingale?”
