I was over here for several month and, if you want an advice, the fastest way to make up some friends here is looking for those who have a discord channel. There are some really nice comunities over here
Also be active on the forums. There are some user you can see them on almost all topics
BTW, i'm a writter (i finished a novel and now i'm translating -sort of- to english and starting to post in tapas). I also like to draw, but i haven't the confidence to publish anything yet ^^' so i have a comisioned comic. More fan of japan than korea, but i hope we can get along!
