@LizScarlet There is no marriage system in ALO. Any rings worn by the characters are just for stat boost (or possibly a sign of a guild leader). The rings Kirito and Asuna wear are AGI or STR boosting rings rings, according to the author. I just don't remember which of the two it was.

@RC 16.5 took place between the scene where Asuna undressed in front of Kirito and the scene where they were in bed and Kirito proposed to her.
