Obsessed

After frozen Elsa is queen and everything is happy. Until Elsa starts having the feeling she is being watched. A sort of love triangle forms except she doesn't love both of the guys but one is obsessed with her, but nobody loves him coz hes annoying and evil, so what would you call that? Because it doesn't sound like a love triangle at all except that there is three people.
Sorry if this sounds like another fic it won't when you start reading it.
Well maybe it will sound like another story but none that I've read. :)
