I've never understood why people are so obsessed mwith the idea of Ayu having kids. I personally don't feel obsessed with the idea. Maybe she feels like she doesn't have what would make her a good mother. I know I don't so I already decided I'm never gonna have kids. We never know what ayu thinks because she doesn't really talk about it. Maybe she decided that it's not what she wants from life.
With or no kids Ayu is stilll a great person, isn't she? ;3
