Being from the void takes interest in a human already at the end of his rope. Its unbearably heavy affection makes a miserable life that much more difficult.

__

A realistic take on an unwanted, daunting attention from a creature of different logic. It's not rosy, it won't be smooth, and there are no instantaneous feelings. As such, the story is barely even a romance - there's struggle, ambiguity and things going from bad to worse on an express train. All that said, there will be semblance of a happy ending.
