One of you has watched the other from afar, absolutely head over heels in love. Their intense charisma and understated confidence gives away the sense that they are so wise, so worldly, that one would even believe they are far older and more experienced than they look.

The other of you has lived a thousand lifetimes, an immortal being of thirst and desire, whose time is running out as the world becomes harder for them to survive in, and those in their neighbourhood are beginning to suspect that they are not what they seem.

One of you has asked the other out on a date. Perhaps this will give one or both of you a chance to satisfy a deep, yearning hunger that loneliness has not afforded for some time. 

Or perhaps it is instead the last night you both will ever see each other again.
