Grammar Focus:
This pattern expresses the length of time starting when a certain action or behavior begins and lasting until it ends. It corresponds to ‘during’ or ‘while’ in English. After nouns, 동안 is added, and after verbs -는 동안 is added.
When used in the form ‘V-는 동안’, the subjects of the first and second clauses can be either the same or different.
• (내가) 한국에서 사는 동안 (나는) 좋은 친구들을 많이 만났어요.

Comparison:
How are -(으)면서 and -는 동안 different?
-(으)면서 is used when one person performs two or more actions simultaneously. However, -는 동안(에) can be used even when the subjects of the first and second clauses are not the same; that is, it can be used to indicate that while the subject of the first clause is performing some action, the subject of the second clause is also performing an action.
