There must be the human protagonist who is living this'sweet life' with the monster. And of course, the monster itself. There might also be supporting characters such as friends or family members of the human who react to this strange relationship. Or perhaps there are other monsters in the monster's world who play a role in the story.
The main characters are most probably the human who is sharing their life with the monster and the monster itself. However, there could be other important characters too. For example, a wise old figure who gives advice to the human about dealing with the monster. Or a rival human or monster who tries to come between the two main characters and disrupt their sweet life. There could also be characters from the human's community like neighbors or colleagues who have different reactions to the situation.
The main plot could revolve around the daily experiences of the protagonist in their life with the monster. It might include how they deal with the differences between them, like cultural or physical differences if the monster has a different 'culture' or form. Maybe they go on quests together or face opposition from the human or monster society due to their unusual bond.
The main characters are likely the girl and her boyfriend who is the'monster'. There might also be supporting characters like the girl's friends or family members who react to the situation of her having a'monster' boyfriend.
Since I don't know the exact story, I can only guess. There's probably a child as one of the main characters who is the owner of the pet monster.
I don't know as I haven't read it. It could be a male and female lead who meet after dark.
The characters included the male lead, Qin Yu, the son of misfortune.| Whoever saw it was unlucky. "My Life Providence is a Monster" by Wei Wukuang. It was a fantasy/high-level martial arts world novel with transmigration, decisive killing, clear thinking, big imagination, and relaxing elements. It was completed and can be enjoyed without worry. [User recommendation: When he woke up, Qin Yu became a Fate Master with a bad fate.] From then on, he was entangled by tyrannical misfortune; Almighty or Supreme Emperor, you'll be in trouble if you meet me. Demons and ghosts, even if they drink cold water, their teeth will be stuffed; The immortals, gods, and Buddhas frowned and shook their heads, afraid that they would not be able to avoid it… You said that I was a jinx, and I said that you were a coward. This was a comfortable story that made others suffer while benefiting themselves. I hope you will like this book.
The main characters probably include the monster girls themselves. Each monster girl might have her own distinct personality and appearance. For example, there could be a mermaid - like monster girl who is shy but has a deep connection to water, and a more outgoing harpy - like girl. The male lead, as mentioned before, is also a key character. He is the one who bridges the gap between the human world and the world of the monster girls, and his reactions and actions drive a lot of the story forward.
The main character is Steve Harmon. He is a young man on trial. There is also Kathy O'Brien, who is Steve's lawyer. Another important character is Sandra Petrocelli, the prosecutor in the case.
I don't know for sure as I haven't read the story. But it could be an ordinary person, like a young man or woman trying to find the sweetness in life.
Since I haven't read the novel, I can't say for sure. But usually in a love - centered novel, there would be at least two main characters, the lovers. Maybe there's a male and a female lead.
I'm not sure exactly as I haven't read this novel specifically. But often in a story about mistakes, there could be a protagonist who is the one making the mistakes.
