One common theme is family. Since the series has strong family elements, fanfictions often explore different family dynamics within the Super Lovers universe. Another theme is love and friendship, as the relationships between the characters are central to the story.
I'm not sure specifically what 'Cap deage' means. It could be a very specific term, a misspelling, or something relatively unknown. It might be a proper name, a local term in a certain area or a very niche concept.
I don't have enough information to say exactly who Cap'n Kathy is. She could be an original character created by the fan fiction writer. Maybe she's a pirate - the 'cap'n' part could suggest that - who has some connection to the wizarding world of Harry Potter.
Well, there's 'The Journey Together'. This fanfiction takes the characters on an adventure outside of their usual setting, exploring new relationships and challenges. It has great character development and an interesting plot. Also, 'Hidden Bonds' is a great read, highlighting the hidden aspects of the characters' relationships.
One common theme could be emotional pain. Since it's 'ren hurt', there might be a focus on Ren experiencing some form of emotional distress, like heartbreak or feelings of betrayal. Another theme could be self - discovery in the face of that hurt. Ren might be trying to figure out who he is and how to move forward after the difficult situation.
Well, its popularity varies. In the niche community of Super Lovers fans, there is a significant group who enjoy reading and writing such fanfiction. They like to delve deeper into the characters' relationship and develop their own interpretations. But in a broader sense, compared to mainstream fiction, it's only popular within its specific fandom. It also depends on how much exposure and promotion these fanfictions get within the Super Lovers community.
The cap man and monkey story is an interesting one. There was this cap man who was traveling around selling his caps. He reached a place near a forest and decided to take a rest under a tree. While he was sleeping, the monkeys in the tree noticed the caps. They climbed down, grabbed the caps, and went back up the tree. When the man woke up, he was confused at first, then saw the monkeys with his caps. He was worried as those caps were his livelihood. But then he remembered that monkeys often mimic human actions. So he took off his own cap and tossed it. The monkeys, being the imitators they are, did the same with the caps they had taken, and the cap man got his caps back.
