Which story is true?

1. When I was 17 years old, I went to Okinawa with my friend's family in the summer vacation. I went to Okinawa for the first time, so I was looking forward to the trip. The first day, I went to the Churaumi Aquarium with them. There are so many fishes and I was glad that I could see famous dugonga sea pigs. It was very cute. Next day, we went to the sea to play marin sports. I walked into the sea and watched many fishes. I had a good trip.

2. When I was 17 years old, I went to Tokyo with my friends for 3 days in the summer vacation.
We went shopping and bought a lot of clothes I like. Second day, I go to the Korea Idol Concert with them. It has four hours, so we can have very enjoyed. I think this was the best concert!! I want to go this concert again.
