This summer, your school held a study tour. The first place visited was the beach.

Meanwhile, you chose to lie under a large umbrella with a large towel covering the sand where you were lying. You could see Jungoo having fun with his friends.

In the midst of your tranquility, suddenly you felt cold metal touching your cheek. You opened your eyes and saw Jungoo lying beside you with his stupid grin. He was holding a can of coca cola for you.

"Take this, you must be hot."

He said as if mocking you who had been sheltering from the sun.
