But It's Not My Fault

"Forgiveness is the final form of love."
Scarlett an honest and bold personality while Ethan a carefree and flirtatious one but is not a playboy.
They both can't seem to figure out what is it they feel when they are together, maybe because they don't want to but still craves for........ love. But when they do understand darkness couldn't hold back anymore.
What is it? Will they understand each other? or was their feeling was nothing but just a mere fling?
