"The moon is beautiful" is famous for being a phrase that means "I love you". It came from Natsume Soseki, one of well-known Japanese authors. The idea is that Japanese wouldn't say "I love you" directly. Instead, they will look at the woman they love beneath the moonlight, and say "the moon is beautiful" to convey their feeling of love.
BUT IS THAT THE BEST THAT WE CAN GET??? GIMME A KISS SCENE DAMMIT!!!!
