Kind of in a similar boat!
Been learning Korean to speak more with my girlfriend’s family, especially since we’re going to Korea soon.
My biggest waves of improvement have come from reading aloud the Talk to Me in Korean books.
I’ve found that getting the structure of the sentences has helped me and then I learn vocabulary by using what I interact with on a day-to-day basis.
There’s also a Korean slang book by Talk to Me in Korean which is really great too! Helps break out of the “learned it from a textbook” sound.
