You know, even if she didn't want to come back, she'd never live a normal life. Everyone would always remember her scandal and not her singing. She can't just go out like that, she should be able to clear her name, dammit!
I've been pondering over this, and I'm afraid that I have to disagree.
Firstly, I don't believe "everyone" would
always remember her smoking scandal and not her entertaining performances, as well as her loveable real-life personality, especially her fellow colleagues and friends in H!P, and of course, her true fans.
Secondly, if she really did not want to return to the entertainment business, after another year or two, I think most people would have forgotten about her, especially if she just remains in Nara-ken for the rest of her life, living with her family, and doing some low-profile job, if she doesn't marry; or she could possibly become a kindergarten teacher at one of the local kindergartens in Nara-ken. If I'm not wrong, I believe Aibon really prefers the much more peaceful and conservative lifestyle in Nara-ken than in Tokyo.
