A Note on Language/Aerelon/Grace Park
It is true that Grace Park is a fluent speaker of Korean, but her English--either as Sharon Valerii or as herself in interviews--bears no trace of a Korean accent whatsoever. I am married to a native Korean speaker, have friends and colleagues who speak Korean either as their first or second language, and have been studying the language for a few years myself, so I am absolutely certain that Korean has no bearing on what might or might not be considered an Aerelon accent.
On a somewhat smaller matter, there is no accepted version of English called "General English," with a capital G. I am willing to accept a lower case g, "general English," to indicate "common sense" notions about the accent/group of accents.
