I am planning to go to Jindo, an island in South Korea, next week.

I used to live in Jindo long ago.

I live in Tokyo.

Once upon a time, there was a big castle in this place.

Once, we used to play in the park every day.

In the past, we used to play in the park every day.

He tends to hold onto past failures.

We went to that island during the summer vacation.

I go jogging every day.

This is a rare book.
