Some ditzy chick in Japan hangs out with an old guy who can't sing very well talking about random stuff. They go to parties and act like twits. Eventually the guy cheats on his wife and everyone mopes around for a while until they go home. TEH END.
An awkward girl starts stalking people in her neighborhood and doing creepy nice things and some childish pranks. She sees an equally awkward boy and stalks him, but is too shy to speak to him. Her slutty friend helps get them together.
Two of my favorite movies!
