Hijacking My Mission

What happens when your childhood love is taken from you? Having the memories you've cherished the most wiped clean?
Being the world's top two assassins, there really isn't much of a love to cherish, but the love of killing. But what happens when they're staring into each other's eyes, the first set of Emerald and Sapphire orbs they fell in love with? More importantly, what would they do when their target, their victim, their first and only love is their next mission?
Jack's new target, Hiccup. Hiccup's new target, Jack. Will their memories help them remember their lost lost? or will their years of training and killing get the best of them.
