Release my Heart From it's Cage

Lillian Hitrel, a human-looking alien from the planet Herentil, comes down to Earth again to be reunited with her human friend Zane Johansen. Her crash landing years ago led her to Earth where she first met Zane, now she's back, for one reason only. She had somehow thought she felt emotions when she was last at Earth. She wants to see if it's possible. Her kind has never been able to feel emotions. It's impossible. Or is it? Due to one certain human boy.
" Hey, Zane..." I mumbled.
" Hm? What is it Lily?" he murmered.
" See those white flying things up there?" I asked.
" You mean birds? Don't you remember?" he chuckled.
" Yeah...I want to be one of them." I sighed.
" Why would you want to be a bird?" he said, still chuckling.
" Cause...I want to be free."
