A myth says that descendants from the land of lacuna cannot co-exist with humans on earth. It makes Jo have to let go of his love and let go with the others. He saw that the woman he loved was happy with another man. It made him so uneasy at the thought of something that would never happen.
Jo is trying to get down to earth because he really wants to see Fani's face. He really misses Fani in his life even though he already has a small family in the land of Neptune. "No woman can replace you in my heart even though she is Rachel, my wife," he mumbled in his heart so very sadly then he saw a baby boy who had been carried by Fani.
