Hi! Seeking to improve my conversational skills

As for English: I I can navigate through basic conversations and understand the grammar fairly well, but I feel stuck. I still stumble over idioms and struggle with the fluidity that a native speaker possesses. That's why I've decided to find a language buddy, I believe that this kind of one-on-one interaction will provide me with the depth of understanding that I can't get from structured lessons alone.

As for Korean and Mandarin: I’m total newbie looking for learning insights from fluent people :)
