What is inside the bottle...

Year 20XX… it was very sultry summer, so I decided to go to the beach with my friends. We ride on friend’s car and leave our hometown. Few hours latter we reached to the beach which was famous of the four meter long nature rock standing straight up to the sky. We spend time at the beach and while my friend was having fun, I went to take foods and drinks from the car. But the way to the car, I saw something is glistering in the sand. I looked carefully and pick it up… It was a glass bin with shells all over. The bin was not clear and closed by a cork so I wasn’t able to look through inside the bin. So I opened the cark, shake the bin down, to see what is inside. After I shake three times, one piece of paper came out. It looked like a treasure map so I checked where the treasure is. I was surprised because the map says that it’s around this beach. I call my friends forgetting to take foods and drinks. The description of the place of the treasure was “The huge owner of the beach will show the place of what you wish to have when the sun sink to the sea…” soon we notice that “The huge owner” was the four meter rock and we also notice “when the sun sink to the sea…” told us that is the sunset. So we wait at the beach until sunset… 6:58. Finally the evening sun sank into the sea. Suddenly the rock shine bright and the dark cold beach have been lightening by emerald shine. Everyone was opening mouthed surprise of the beautiful scene. And this became a treasure of memory but not a real treasure…
