Pain First, Love Last [COMPLETED]

"falling in love is fun."
Is what they said.

They both have a dark history, a grim present and are both trying to fight against the problems they have to face at night while trying to be normal during the day, to make sure no one finds out their secrets. Y/N, a girl who's used to not having anyone, always alone. Until one day, someone comes into her life and is just as twisted and cold-hearted, like her. They are similar in so many unexpected ways. Until they find out they are destined to be enemies.
