Watching K-dramas and listening to K-pop has really helped me get a grasp on how the native speakers speak, also interviews and game shows with Korean Idols and English subtitles; like Man on a Mission, and After School Club. Some of my favourite K-dramas are To Be Continued, and I Am Not A Robot, also any of the K-dramas they have on Netflix are really helpful.
