Pein

You were in pein's office doing some paperwork until pein came back from holding a meeting, you had a song stuck in your head. You had started to hum it and you didn't even notice you had started to sing,
I do believe in the light, raise your hands up to the sky
The fight is done, the war is won, lift your hands towards the sun
Towards the sun, (it's the moment of truth and the moment to lie
It's the moment to live and the moment to die, the moment to fight)
Towards the sun,
Towards the sun, (it's the moment of truth and the moment to lie
It's the moment to live and the moment to die, the moment to fight)
The war is won (to fight, to fight, to fight, to fight)
Pein " you have a lovely voice my dear ", you got spooked and turn around to see pein and you blush and said " oh uh thank you ", pein " it's no problem, now let's get back to completing this paperwork ".

Obito/Tobi

You were in Tobi's room waiting for him to return from a mission, he was talking a while and you decided to sing while waiting for him.
Why is everything so fucking hard for me?
Keep me down to what you think I should be
Must you tempt me and provoke the ministry?
Keep on trying I'm not dying so easily
You then heard someone say " that was amazing (y/n)-chan, you have a pretty voice ", you turn around to see Tobi standing there and you said " thanks Tobi ".

Deidara

You were in the field where you and deidara usually hang out, you were waiting for him to get there, for he said to meet him and you were quite bored, so you decided to sing while waiting.
Give me a reason to believe
Cause you don't wanna see me leave
I can't stop the rain
But I can stop the tears
Oh I can fight the fire
But I can't fight the fear
When you finished someone said " that was amazing un ", you turn around to see deidara leaning against a tree crossing his arms, you blush and said " thanks deidara ".

Sasori

You were in your room on your bed hugging your pillow, for some strange reason you started to feel nervous but didn't know why, and you usually sing to get rid of it so you decided to do that.
She won't make a sound
Alone in this fight with herself
and the fears whispering if she stands she'll fall down
She wants to be found
The only way out is through everything she's running from
wants to give up and lie down.
When you finished someone said " I'll always be there, so you don't need to worry about any of that ", you blush and turn around to see Sasori looking at you, you then said " o-ok ".

Hidan

You were waiting for hidan in his room, for he told you to wait for him in there while he went to go do sacrifices you were getting bored, you closed your eyes and decided to sing until he came.
Gone by
Making my way back from the madness
Shifting my thoughts from the blackness
And the sadness, but the fact is
I'm swinging through life like a clenched fist
Fuck sanity, I wanna bleed
Can't kill the pain, it's everything
It's all I feel
It's what I breathe
Turn the hate I breed into what I need
Heavy is the hand that points the finger (Finger)
Heavy is the heart that's filled with anger (Anger)
You then heard someone say " damn you got a good voice ", you open your eyes to see hidan in front of you smirking, you then said " of course I do" you smirk at him.

Kakuzu

You were getting ready to clock out for the day, even though you still you joined the akatsuki you still work at the collection office, you were bored for you still had ten minutes left, you were bored for nothing was happening, you sign and decided to sing.
Where's the truth?
Where does it lie?
All this smoke is burning my eyes
Fear on the left, fear on the right
Money is power and power decides
Some are more equal than others
Everybody, everybody lies
Everybody, everybody buys it
Everybody, everybody
When you finished you heard someone say " you have a amazing voice ", you turn look around to see kakuzu at the entrance with some body, you then said " are you here to say how you like my voice, or do you need help with that ", he chuckles and walks up to you.

Kisame

You were by the lake at night waiting for Kisame, you two agreed to meet up here after he was done with his mission, you were starting to get bored so you decided to sing.
No need to hear your voice
Or see your face
To know that you are with me
No need to kiss your lips
Or hold your hand
To know that you can feel me
I know that you can feel me
When you finished you felt someone hug you from behind, Kisame " Your right there I don't need you close to me know your with me ", you blush and said " the same for you ".

Itachi 

You were in the forest waiting for itachi he told you to meet up with him in the forest after his mission, you were skipping rocks, but you eventually got bored, you sign and close your eyes, you started to sing.
Will you love me or leave me forever?
Will you love me or leave me forever?
Will you love me or leave me forever?
Will you love me or leave me forever?
Will you love me or leave me forever?
Will you love me or leave me forever?

When you finished you smiled and someone said " I'll never leave you I'll always love you ", you open your eyes suprised and see itachi looking at you with a small smile, you then blush and said " yeah ".
