This is really sad. ): I was rooting for them in the future, but her explanation is equally very understandable, I will support Ayu and wish Mannie all the best, too. <3
Also, I don't think it's fair for people to go "I knew this would happen, I never liked Mannie". He's not the bad guy here, he never treated Ayu wrongly, they just grew apart. That's what happens when you live in countries separate sides of the world. XD
I don't think it's neccesary to be hateful towards him like that, and Ayu wouldn't want you to be, either. Forgive me if I have missed the ball here, it's okay if you dislike Mannie, but don't make him look like a bad guy. XD
I hope Ayu and Mannie find new loves they can keep close, and still remain friends.

I won't inquire into her personal life or decisions, that's not my right, but I will support her, I think she's made the best decision for both of them. It's quite obvious from what's she's said, that Mannie wishes to stay in the USA, and Ayu wishes to stay with her country. That's just what happens.
I know Ayu is one tough women, but I also want to give her a big hug, hahaha.

It can't be easy.
