antique bakery movie

I've got to admit that I almost want to see the Korean live-action Antique Bakery movie after watching the trailer, in spite of the fact that the manga did nothing for me and the "mustache" on the owner dude is lame. But the song! It is so inane and happy! And it seems to push the gay more than I remember the manga doing...

It must be available on the internet already. Has anyone seen it? Is it any good? Or at least good enough to live up to the trailer?
