I'm looking for a noun that describes a person A, who loves person B, but person B doesn't reciprocate. Person A suffers because he or she can't have person B and is not interested in relationships with others.
The shorter the word, the better (ideally — single word).
Sample use in a sentence:
It poured as if it rained tears of all people who suffered from unrequited love.
I need a substitute for people who suffered from unrequited love.

Collins gives the meaning :
for the word 'lovelorn'.
Also, Cambridge
But note that both sources are defining the emotion (miserable and sad) of the recipient (or rather non-recipient). They are not defining the state of being in a situation of unrequited love itself.
However I think that the noun, the lovelorn, answers the OP as the question was about a 'person who suffers'.
