The Chinese music industry is, unfortunately, a mess. It's a given that -M will be the lesser group by a mile in terms in popularity. I hope SM has a plan for them in case it doesn't work out in China, which it very well might not. Maybe they'll eventually bring the -M members back to Korea and make one 12-member EXO, the new, less basic SuJu?
Hopefully that is an option.
I'd think it'd work out well too.
I'd hate to see Exo-M dragged through the mud, then fired.
