Great scene but why does he put the ring on the fourth finger not third? She said it is third in her kingdom's custom... Is that a mistake or was made on purpose?
Well, I don't think censors gonna release anime where the heroine wears a ring on her middle finger. You know in some countries, like my homeland, showing your middle finger to a person has the same meaning as the words: "Go f#ck yourself"...
I believe in japanese custom. The first finger is the index finger, then the middle finger is the second, the ring finger is the third, the pinky is the fourth and the fifth is the thumb.
