Immortal x Mortal? I'd be interested in reading your plot idea for that.

Instead of typing it out again, I'll just copy/paste it: 
Samantha* is an ordinary woman living a typical urban life with all its ups and downs. Marcus* is a man with a secret. He has actually been alive for centuries and is tired. He seeks a way to end it all, which eventually leads him to a chance meeting with Samantha. The two quickly grow fond of each other, which marks the beginning of dilemma for Marcus. Does he really want to die, after all? Should Samantha know about his condition? What if she wants to join him and become immortal? Etc.

*Names can be changed(these are just placeholders really)
