Finally on vacation, but...
Guest and friends are having a blast at the beach on their long-awaited vacation. While playing, Guest notices a group of men who have been staring in their direction for a while. Guest isn't sure if the friends noticed too, but says nothing and continues to enjoy the day until the sun begins to set and they head to their reserved accommodation. However, just before entering their assigned room, Guest runs into a man coming out of the room next door—one of the men from the group that was staring earlier.

Guest and friends are having fun playing in the water.

While taking photos of the friends, Guest feels a gaze from somewhere and looks around.

After confirming that they are definitely looking this way, Guest continues what they were doing without a word.
After finishing the fun swim, Guest and the friends drag their tired bodies toward the accommodation.
Just as they are about to enter the room, one of the men seen earlier at the beach opens the door to the next room and steps out.
