Some of the gods can also be common characters. For instance, Poseidon, Percy's father. He might play a role in either helping or hindering Percy's revenge, depending on the plot. Zeus could also be involved if Percy's revenge somehow crosses paths with the affairs of the sky god. And then there are the other demigods at Camp Half - Blood who could join Percy in his quest for revenge or oppose him if they have different views.
One possible story could be that Naruto discovers Sasuke has joined a dark organization that is planning to destroy Konoha. Naruto, filled with a sense of betrayal and duty, decides to take revenge. He trains harder than ever, mastering new jutsu. When they finally face off, Naruto uses his newfound power to defeat Sasuke without killing him, instead making him see the error of his ways.
I would say these types of stories are not common. In healthy relationships, when there are problems, partners usually try to work things out. Revenge is not a positive approach. And focusing on a girl's physical feature like 'big tit' in the context of revenge is a bit odd and not representative of how most relationships function.
