Chapter 3

Yuki sees James and a group of his friends beating up Lotor James Stop you're hurting him Said Yuki come on babe we are just having fun and plus he is a nerd but still, he acts like he is tough said James we broke up remember you cheated on me with Allura who was Lotor girlfriend at that time I caught you kissing her.
Allura walks over to James and pushes Yuki down onto the floor don't talk to my boyfriend like that Said Allura, Yuki stands up, and then she starts to sing
Mama always told me
That I was too naïve
I said don't you worry
Didn't think that l'd be
Broken down and crying
"Help me"
Wreaked? Check
Then Yuki stops and goes to Lotor and helps him up to his feet then she continues to sing again
Heart? In debt
All you do is come around
Just came here to collect
Wreaked? Check
Heart? In debt
Don't you know that
I cried tears of gold for you
I sit here poor for you
Collect my pennies and my dimes
That's why you love it when I cry
Platinum love for you
I'd give no less for you
Generosity's my enemy
So I'm broke and
Your heart's rich because of me
And the worst part is, I know it's never gonna end
I keep coming right back like a maniac
I keep coming right back like
And the worst part is I'd do it all over again
No, the worst part is I know it's never gonna end
I keep coming right back like a maniac
I cried tears of gold for you
I still here poor for you
Collect my pennies and my dimes
That's why you love it when I cry
Platinum love for you
I'd give no less for you
Generosity's my enemy
So I'm broke and Your heart's rich because of me

 The song tears of gold belongs to Faouzia 

Then Yuki and Lotor walks away from James and Allura at lunch Yuki was in the music room again and play the piano singing Lotor was watching her sing from the doorway
You shout it out, but I can't hear a word you say
I'm talking loud, not saying much
I'm criticized, but all your bullets ricochet
Shoot me down, but I get up
I'm bulletproof, nothing to lose
Fire away, fire away,
Ricochet, you take your aim
Fire away, fire away
You shoot me down, but I won't fall
I am titanium
You shoot me down, but I won't fall
I am titanium
Cut me down, but it's you who'll have further to fall
Ghost town and haunted love
Raise your voice, sticks and stones may break my bones
I'm talking loud, not saying much
I'm bulletproof, nothing to lose
Fire away, fire away
Ricochet, you take your aim
Fire away, fire away
You shoot me down, but I won't fall
I am titanium
You shoot me down, but I won't fall
I am titanium
I am titanium
I am titanium
Stone hard, machine gun
Firing at the ones who run
Stone hard, as bulletproof glass
You shoot me down, but I won't fall
I am titanium
You shoot me down, but I won't fall
I am titanium
You shoot me down, but I won't fall
I am titanium
You shoot me down, but I won't fall
I am titanium
I am titanium

the song titanium belongs to David Guetta and Sia   
'Hey I thought I told you to stay away from my sister' said Keith Yuki
