I don't get why Maro says what she did is unforgiven considering other ZOC members are in relationships/ married aswell and Watanabe was seperated already.
His divorce is really just formal here no betrayal since you can't expect ppl to be single forever.
That's the crux though--until his divorce is final, he's not single. It's unfortunate, but Japanese celebrities are held to a high socially conservative standard.
It's not like his wife doesn't know they are getting divorced, so she's not being hurt by any of this (at least no more than their breakup has already caused, I don't know the specifics of their situation). Celebrities all over the world are held to ridiculous standards by the press but it seems obvious here that no harm is being done.
