With ABC Family's summer lineup of teen dramas under way, the romances on shows like Pretty Little Liars get me all nostalgic for some of my past favorite young couples. If one thing hasn't changed since the mid-'90s and early '00s, it's that these soap operas starring teenagers are always filled with intense, over-the-top relationships. So maybe Hanna and Caleb or Spencer and Toby can learn something from these other pairings that fans used to obsess over. (Though when half of the duo is a grown adult who used to be his underage girlfriend's teacher, it might be a bit more tricky... Sorry, Aria and Ezra.)
