^ never thought of it this way but it makes sense. This would explain why maro invested so much in the relationship, and then all the angst for it ending. Plus ayu seems easily a person who feels SO MUCH but who could change her feelings in a blink of an eye, as you said. Not blaming her, I honestly would have done the same probably. XD

edit: do you think that something had been going on as well with shu-ya in the past or in the present?
I just... I've always thought that they HAD something, even tho it was just sex or whatever. The chemistry was there. And then he left so suddendly, more over after the scandal with maro and ayu divorcing etc. When ayu divorced she was also seen with shu-ya everywhere, remember the photos? Then Maro, then she married and BUM, shu-ya is forever gone. It seems fishy to me, like he would have another reason to live rather than to focus on his 'solo' activities. Maybe he was hurt emotionally?
