After they reached her balcony, Cathy turned back into a human while Lucky climbed up the rope with the help of Cathy then Cathy letted him sit down on her extra seat. "Okay, so I'll grab the Mystical Gems and Supernatural Powers book. We might have gems or powers? Who knows"she said as she handed Supernatural Powers book to him. After hours of reading, both of them saw something on the book that they are reading. "Okay you go 1st"she said, then he read it "Have you been feeling that they are in trouble or they need help? It must have been the Destiny Bracelets!"then he got confused,"Wait, Linked Bracelets?"then she looked at page 901, she looked at the picture and the gems and the structure were the same as the one they are wearing, she then read it "This bracelet will change it's design according to the future wearer of this bracelet.

To those who wore these kind of gem bracelets and had a gut feeling of one person's feelings or situation.

The bracelet only sends this signal when it's really important or an emergency.

These bracelets do not appear to human eyes if they are not the future wearer, it only appears to those who MUST wear it. Remember, it is no coincidence if you found this. The bracelets really chose you and your fellow/partner."then both of them looked at each other. "Woah..."the two said, then Lucky smiled "Hey, we've been friends for a week and became best friends after a month, but hey... I'm ready to take the big leap!..."he said the she was confused. "What are you talking about?"she asked then he continued "Will you be my girlfriend?"then Cathy accepted it and hugged and kissed him in the cheek. "But... Are we really a perfect couple? We are in different worlds Lucky, you a mermaid and I a human..."
