Jackson was head over heels in love with Serenity, but to her, their relationship was just a mistake.
The woman he loved the most in the world was begging him to set her free. What could be more ironic than this?
"Okay. I'll let you go." Jackson heard his own voice saying, "From now on, I'll have nothing to do with you!"
His relationship with Serenity, whether like lovers or siblings, would cease to exist, just like two parallel lines that would never meet or intersect.
