Tear Jerker: West Side Story
West Side Story. The death at the end combines the music of "Somewhere, there's a place for us, somehow, someday, somewhere," and Maria's rhapsodic affirmation of her love: "I have a love, and it's all that I have."
"One Hand, One Heart" moves this troper to tears nearly every time she even listens to it. Make of our lives one life / Day after day, one life. / Now it begins, now we start / One hand, one heart, / Even death won't part us now.
"I didn't believe hard enough."
SECONDED. In addition: "Yes... We can... We will..." Y'know what, just the entire ending.
