This video was made by a long-time friend of the girl, who wanted to be more than a friend to her. She told him she wasn't interested in him, only as a friend. After her refusal he started to notice something strange about her relation with her own brother and everything became evident when a group of friends invited her for a week at the beach and she ended up bringing her brother. During that week he noticed every day for about 30 minutes both disappear from the group so he decided to follow them one day. They went to a desert beach and he finally found what kind of relation she had with her brother.
