Romeo X Juliet/Tear Jerker


 * When Juliet and Romeo meet and fall in love in Romeo X Juliet. Because in this version they're actually likeable characters, and the knowledge of what's to come just kills you.
 * Episode 11, the "Romeo and Juliet are officially a couple" episode, consisting of mainly the two leaving the city for a day to just wander around all lovey-dovey. Like the last example: nothing obviously tragic, until you remember what you're watching.
 * Episode 15. Petruchio.  *sob*
