also she said she won't participate in things that have morning musume.
if i remember right
I don't remember this occuring at all. If you had a source, I'd like to see it. I think maybe you took something a little too literally. Like, maybe it said that she wouldn't appear with morning musume (and by that, I mean as a member).
The way you have it means she will never again be on a show that has morning musume on it, which could not possibly be correct.
I'm not saying she'll be on Hello! Morning anytime soon, but I'll leave the door open for her being able to at some point.
