How do you say "back then" or "in those days" in Korean? Someone wrote these two sentences in the Notebook Entries section: 10년 전에 미나 씨는 학생이었어요. 10 years ago Mina was a schoolgirl. 10년 전에 그녀는 키가 작고 통통했어요. 10 years ago she was short and plump. In English, we would avoid repeating "10 years ago" and replace it with a phrase such as "back then" or "in those days". "Back then, she was short and plump." "In those days, she was short and plump." How would you express this idea in Korean?
