I don't know for sure, but there could be a jilted lover as one of the main characters, the person who they are seeking revenge on, perhaps a new love interest of the person they are targeting too.
I'm not sure who the main characters are as I haven't read the 'Review Revenge a Love Story'.
I don't know for sure as I haven't had access to this story. But I can assume there would be at least one cheerleader as the main character, probably the one seeking revenge. There might also be the person who broke her heart, could be a love interest, a rival cheerleader, or someone from outside the cheerleading world.
As the title is 'Manan ff the revenge love story', it's likely that Manan is a central character. Maybe there's a love interest, someone who was involved in the situation that led to the need for revenge. There could also be friends or family members of Manan who play a role in either supporting or trying to stop the revenge plan, and in influencing the love aspect of the story.
Since I haven't seen it, I can only guess. There's probably the cheerleader who is seeking revenge. Then there must be the person who broke her heart, like her ex - boyfriend or love interest. There might also be some friends or rivals within the cheerleading squad who could be either helping or hindering her revenge plan.
It could be the jilted lover. The one who was left broken - hearted and is now full of rage and a desire for revenge.
Most likely the king cobra itself is a main character. And perhaps there are some humans or other animals that the cobra has a conflict with.
In the 'Jaws the Revenge Novel', there could be a family that has some history with the sharks from the previous 'Jaws' stories. Maybe a father who was involved in the earlier shark - hunting expeditions. There might also be a local sheriff or a coast guard officer who is responsible for the safety of the area. And of course, there would be the shark itself, which is almost like a character with its own motives of revenge. There could also be some local fishermen who are the first to notice the strange behavior of the shark and try to warn others.
In this type of novel, the main character is often a person with a past full of pain and injustice. They are the driving force behind the revenge plot. Then, there could be the ones who caused the initial harm, which could be a group or an individual. Additionally, there might be other characters like a mentor - type figure who gives the main character advice on how to carry out the revenge in a more effective way, or a love interest who either supports or complicates the revenge journey.
Since I haven't read the novel, I can't say for sure. But it could be the parents of the baby if the revenge is related to something that happened to their child. Maybe there's also an antagonist who caused the situation that led to the need for revenge.
Obi - Wan Kenobi is also important. He is Anakin's mentor and tries to stop his fall to the dark side.
