What do you think would happen with Henry and Zhou Mi if Hankyung really leaves Super Junior?

Okay so I'm starting to lose faith... I don't think he will come back. Of course I hope he will, and I try to believe it with all my heart, but I can't.
So... What do you think would happen with Super Junior M, if their leader is gone? Do you think they'll keep their activities in China even without Hankyung? Or do you think they'll just stop their activities as SJM and just stick to SJ?
I'm asking this because I really love both Henry and Mimi and I don't want them to have to leave just because of Hankyung... the last I heard of Mimi was when I saw the previews to that show I forgot the name of, and I haven't even seen the show even if it came out- I don't know when it will if it hasn't.
I follow Henry on twitter and as far as I know he's still in Canada with his family... So he's really not doing anything as far as I know.
What do you think? Is there a chance that SJM will keep their activities [...or maybe that Henry and Mimi would join SJ~ LOL I'd love that. Especially if it means QMiMin would be together ;D] or is it the end of the two of them?
........ Or do you think Hankyung would actually come back, eventually? T_T [Omo I really, really, really want him back. I've cried so many times because of it.... I want HanChul together again T___T]
