I don't know why the Sasshi' fans hates Tomochin, especially after her "scandal". Why?
Well, Tomo had hed own boyfriend scandal months ago, she was
rumoured to be dating Takahiro of EXILE, but the incident didn't went as serious as Sasshi's.
Why? Lack of proofs (it's still rumoured they are together, and even if they are, they are being too careful, because both have active careers; dating or not, Sasshi wasn't careful in keeping everything completely secret and involved herself with a fan -something that is against the rules, just like having a boyfriend-).
With Sashihara transfered to HKT it doesn't mean she's back to Kami7, because technically, Sasshi didn't lost her ranking; but yeah, wonder how things will go to her. In case she's having really a relationship, I hope she continues being careful in not getting caught, because the press will keept both eyes open to watch the girls' moves during the following months.
