Ironically, I am writing a romance novel so, it's easy to know who's the pairing here
Life and Death are two different people. Death is cursed to kill anything she touches so she separates herself from everyone. Life is cursed to mentally or physically ruin anyone she touches. But she is able to reverse her curse, leaving the person better than before. What happens when two complete opposites fall in love and can't resist each other, even if they're not aloud to touch each other? And what happens when the struggles thrown at them threaten to mess up everything they have worked for?
