Ok, this buying a house thing is just a tad bit worrying. I mean, I want Ayu to be happy and all, but I selfishly don't want her to settle down.
I'm normally not the kind that gets into these rumors, but this relates to the buying of the house - when my Mom(who is a big Ayu fan too) saw the latest music station performance she speculated that Ayu might be pregnant. Not just because of the baby doll dress, but to her, she thought Ayu's hands and face looked puffier than usual. Now Ayu is also showing up in her next magazine cover in a baby doll dress.
Treat that all with a grain of salt though. Until Ayu confirms or denies anything, it's all just speculation.
