Love is great in real life, or whatever, but it is so much better with a professional soundtrack and sweeping visual effects. Call us crazy/out of touch/possibly delusional, but we said it. So, it follows that unrequited love — while plenty painful in reality — is even worse when experienced vicariously through a fictional couple that never actually gets together because the universe is against all that is good. (Universe! You always ruin everything!)
The will-they/won't-they aspect of some of these relationships kept us enraptured, even if the pairings never actually got it on. Censors, fans, cancellations, and just bad decision-making kept these lovers apart, and our hearts just haven't been the same. Because, night after night, in our dreams, each of these unfortunate lovers will always be meant to be.
