Princess Waltz/Heartwarming

"Arata: I'll take responsibility. I'll dedicate the rest of my life to making you happy."
 * Crowning Moment of Heartwarming: Arata's speech about how it doesn't matter if, Chris is Chris and Arata wants them to be together forever.
 * When Arata accidentally steals Lun Lun's First Kiss, she starts making a big deal out of it...which, after a moment's hesitation, leads to him proposing on the spot. Lun Lun is rendered speechless, though she does let him off the hook.
