Ayu got engaged today! (12/12/2013)

If she did get married without any notice, when people finally found out there would be comments like "she doesn't care for her fans", "she's embarrassed of her husband being so young", "she was embarrassed about her love life being such a mess on the past 2 years", "she didn't want people to find out because she was afraid it could fail like her previous marriage", etc... now THAT would have been a mess imo.
It's better this way, if she can keep it like a simple announcement to let people a aware she's going to be married and that's it. I just hope she keeps it private after this announcement.
