This is a section that I like from Sejong Institute: 한국어 한마디 (Korean: 1 sentence at a time for everyday life). You can learn 60 short Korean phrases in total, with sample conversations.

This series is under “Introductory Level” tab on Sejong Institute’s website, with romanization, translation in 9 languages including English and Indonesian, and also narration/explanation in Korean, but Korean sentences such as 요즘 정신없이 바빠요 or 요즘 기타에 푹 빠져 있어요 are polite expressions that could make your Korean sound fluent and natural. ###
