Does Ayu have a brother?

[yagovg]

I read in a thread something that caught my attention, It is possible for ayumi to have a brother (or a sister).

As far as we know, ayu's father left her and her mother when she was a baby. Well, her father could have found a woman and maybe they had children, so it is perfectly possible for ayumi to have a brother (or more), think about it, maybe you are ayu's brother or sister.

What you think about that? Had you ever wondered that? I never thought about that possibility, but it is interesting to discuss about it. Maybe ayu's brother is her fan lol. Maybe ayu's brother has been in some of her concerts, maybe he lives near to her... we can only speculate but it is really frightening to consider that she has a brother somewhere. I want to hear your opinions, so let's start.
