There's also the 'external conflict' trope. There might be some outside forces, like family feuds or social differences, that contribute to their initial enmity. But as they overcome these external conflicts together, their relationship changes. For instance, in Romeo and Juliet, the family feud between the Montagues and Capulets is an external conflict that adds to their initial difficulties, but their love overcomes it in a tragic way.
The 'forced proximity' trope is common. Like being locked in a room together. Another is the 'redemption arc' where one of the characters changes for the better. And of course, the 'love - hate banter' which shows their initial animosity but also the underlying attraction.
The 'love - hate relationship' is a very common trope. They constantly bicker and seem to dislike each other, but there's an underlying attraction. And then there's the 'protective bully' trope. Even though they were mean before, when someone else tries to harm the victim, the bully becomes protective, which is a sign of the changing relationship.
One common trope is the Chosen One. This is a character who is destined to save the world or fulfill a great prophecy. For example, in 'The Lord of the Rings', Frodo is kind of a Chosen One as he has to bear the One Ring to Mount Doom. Another is the Magical Mentor, like Gandalf in the same series, who guides and teaches the hero. And then there's the Dark Lord trope, Sauron in 'The Lord of the Rings' being a prime example. He is the powerful antagonist that the hero has to defeat.
One common trope is the 'enemies to lovers' situation. In this, the two main characters start off disliking each other intensely, perhaps due to a misunderstanding or a rivalry. For example, in many historical romances, a nobleman and a woman from a rival family might begin as enemies but as they are forced to interact more, they discover hidden feelings for each other. Another is the 'love triangle' where the protagonist is torn between two potential love interests. It adds drama and tension to the story. And the 'Cinderella' or 'rags - to - riches' trope is also popular, where a character of humble beginnings catches the eye of a wealthy and powerful person.
One common trope is 'Love at First Sight'. In many romance novels, the protagonists meet and are instantly smitten with each other. Another is the 'Forbidden Love' trope, where the lovers are kept apart by social status, family feuds, or other external factors. And 'The Big Misunderstanding' is also popular, where a simple miscommunication causes a rift between the couple.
One common trope could be the 'Save Scumming'. In repeat visual novels, players often use this method. They save at different points in the game and then reload if they don't get the desired outcome. This allows them to explore different story branches and endings more easily.
'Cruel Prince' by Holly Black also has elements of enemy to lover. Jude, a human girl, is in a world full of faeries who often treat her poorly. She and Cardan, a faerie prince, have a very antagonistic relationship at the start. But over time, their relationship becomes more complex and develops into a love story.
Lord Lamp was talking about a novel called " Family, Enemy, Lover ". This was a story about a younger brother and sister. The story was about the heroine who discovered that her mother had an affair with a strange man when she was young. She reported her mother's lover, causing her mother's reputation to be damaged. Her parents divorced, and her younger brother was taken away by her mother. When she became an adult, the heroine reunited with a young boy and began to fall in love. However, the female lead was involved in a major incident, causing her reputation to be damaged and she was suspended from her duties to pay compensation. In the end, the female lead revealed that she had always suspected that the boy was actually her younger brother and that he was here to take revenge on her.
Family, enemies, and lovers was a novel created by Lord Lamp. The content of the novel was mainly about the love and hatred between the sister and the brother. Her sister had doted on her brother since he was young, but when she was thirteen, she found out that her mother was having an affair with a strange man, and her brother was that man's son. The story began with the reunion of the two adults. They launched a series of tit-for-tat competitions and fell in love with each other. However, the specific plot and plot development needed to be read in full.
One common trope is the 'locked room mystery'. It presents a situation where a crime, usually a murder, occurs in a sealed or seemingly inaccessible space, like a locked room. Another is the 'unreliable narrator'. This character may be lying, misremembering, or have a distorted view of events, which adds to the mystery. And the 'red herring' is also popular. It's a false clue that misleads the detective and the readers, making the plot more twisty.
