They are called petrarchan lovers.
A very famous one, kinda modernized.
Romeo: Oh Rosaline, Oh Rosaline, why won't you look my way Rosaline?
you may not know me,
or, You may even hate me,
but I will give you the moon,
the earth,
my heart,
Everything!
I left you a Valentines day present, but you thanked Tybalt for giving it to you.
though he knows he didn't give it to you, he still capitalized on it.
I know that cock blocker fucked you, but will you look my way, oh Rosaline?
Too bad NTR games you cannot do what Romeo did to Tybalt.
