Konno was good as a member of MM, but seriously I can't imagine her going solo, or doing dramas or hosting tv shows. She would have ended up doing nothing, just like Kei, and that would have been terrible waste for her abilities.
So, I think it's the best solution for her to continue her studies now, when she's still got the chance.
I wish her good luck.
The same goes pretty well for Makoto as well. But because she never was any star in MM or H!P, her graduation because of "studying abroad" feels a bit like "firing" her
I'll hope this isn't the case though.
