That's...interesting.
I thought most groups still let members enroll in performance arts schools like Hanlim and SOPA.
I think this is one consequence of debuting groups too young. They do end up rather naïve to the world.
This is also why a lot of people have a hard time finding a job if the whole "idol" thing doesn't work out. They have basically been groomed for the position from a young age, and they have had everything taken care of by their managers.
I don't think H2H will have the first issue since they have already started off well, and SM is going to push them to make sure they are relatively successful. But, yeah, I hope they do have people in their lives to keep them grounded. There is a lot you can learn by going to school and interacting with classmates, but it's not the only way as long as they get some kind of real education.
