College couples enjoying a romantic kiss at the lovers point

A few college couples are enjoying a romantic kiss at the lover’s point. It’s just after college hours and so they come here for some romance. One of their friends is still single and is feeling a bit jealous, and so he starts to tease them by making a video. But he hardly bothers them, they are on fire and are not going to let anyone disturb them. Though one of the couples is a bit shy and one other guy is trying to hide his face. I wonder why.
