I would suggest that you add a little more context to make it sound more natural.

For example; I went to a *beautiful* cafe overlooking the river.
*The air felt more refreshing since I’m done with finals*.
*I started chatting with the cafe owner about school and possible future plans and that’s when she told me about her daughter.*

Extra context helps the paragraph feel more natural and paints a clearer picture rather than just a few sentences of information.

좀 더 자연스럽게 들리도록 컨텍스트를 추가하는 것이 좋습니다.

예를 들면 다음과 같습니다. 나는 강이 내려다 보이는 *아름다운* 카페에 갔다.
*결승전이 끝나서 공기가 더 상쾌 해졌습니다*.
*카페 주인과 학교와 향후 계획에 대해 이야기하기 시작했고 그때 딸에 대해 이야기 해주었습니다.*

추가 컨텍스트는 단락이 더 자연스럽고 몇 문장의 정보가 아닌 더 명확한 그림을 그리는 데 도움이됩니다.
