Alex went inside his room and slowly opens the window. From his location, he can see Greg and Caroline talking beside the pool.
Caroline seemed to be smiling while talking to Greg.
It looks like the couple was having a pleasant conversation. It can't be denied that the two people talking in the pool right now were each other's... first love. Before they got separated, the couple was madly in love and planning to get married, just that Greg was involved with illegal drugs and the cops were hot on his heels, the only reason why the two lovers got separated.
It's a pity that when his brother found his first love again, it's too late for him, unfortunately, he had no idea that Caroline was already married to another guy.
