Is it possible for active groups and idols to learn English and speaking the language fluently in the middle of their career? with intentions to expand to the global market you'd reckoned by now that agencies would try to let one or two members in their groups learned the language in degrees that they would eventually be fluent with and able to comprehend it further so that they can easily interact with fans who speak and understand English and also international media.
Is it possible?
can it be done?
or is it a preserve korean image / nationality thing? ...where this kind of integration is considered discouraging, just a waste of resources, and completely uneccessary?
and if so, why'd you think agencies haven't done something like that? or why isn't it a popular thing to instill to their groups?
If anyone can cite notable agencies and groups who have done this and went through this process? why do you think it hasn't been replicated by some of its contemporaries?
