Often, towards the end of a love triangle novel, there is a resolution. It could be that one character finally wins the love of the desired person. Or, in some cases, the person at the center of the love triangle realizes that neither of the two options is right for them and decides to be alone. Sometimes, the relationships are transformed in a way that all three characters end up having a different kind of relationship with each other, not just centered around romantic love.
In fanfiction, the development of the Katniss - Peeta - Gale love triangle can start from different points. Some might begin with Katniss's pre - Games relationship with Gale, showing how their bond was formed through hunting and surviving in District 12. Then, the Games enter the picture, and Peeta comes into her life in a very dramatic way. As the story progresses, Peeta's love for Katniss becomes more and more obvious, while Gale is waiting for her back home. Fanfic writers might make Katniss struggle with her feelings as she experiences different situations with both of them. For example, a shared moment of vulnerability with Peeta during the Games could make her question her feelings for Gale.
Often, one person makes a choice. For example, in some stories, the female lead chooses the guy who she realizes truly loves her and has her best interests at heart.
Often, one person in the triangle is left heartbroken. For example, in 'Romeo and Juliet', Paris is left out as Romeo and Juliet pursue their love and ultimately die together. In some cases, the main character realizes who they truly love and choose that person. Like in 'Pride and Prejudice' Elizabeth chooses Darcy in the end.
Often, it ends with the mystery remaining unsolved. The disappearances continue to baffle the characters in the story, leaving them with a sense of fear and wonder about the Bermuda Triangle.
Often, they end with a resolution of some sort. For example, in 'Pride and Prejudice', Elizabeth and Mr. Darcy end up together, while Mr. Wickham is sort of pushed out of the picture. The good - hearted characters usually get their happy endings, while those with bad intentions or who are obstacles in the relationship don't fare as well.
Often, one person in the love triangle ends up with the main character they are meant to be with. For example, in 'Inuyasha', Inuyasha finally chooses Kagome over Kikyo. Another way is that the character in the middle realizes they don't have romantic feelings for either of the other two in the triangle and decides to be alone or just be friends, like in some less - common storylines.
They often end with one person making a choice. For example, the person at the center of the triangle decides to be with one of the suitors. Or it could end with all parties realizing it's too complicated and walking away.
Often, the protagonist makes a clear choice between the two love interests. For example, in some novels, the girl might realize that one guy has been there for her all along and truly understands her, so she chooses him over the other.
They can end with one person making a selfless choice. For example, one of the people in the triangle realizes that their friend really loves the person more and steps aside. Another way is that the person who is the center of the triangle chooses one of the two. Sometimes it's a happy ending where the couple stays together, and the other person moves on.
Often, it starts with their mutual respect. Luffy respects Robin's intelligence and strength, and Robin respects Luffy's leadership and unwavering spirit. Their relationship then grows as they share adventures and overcome challenges together. For example, in many fanfictions, during a battle where Robin is in danger, Luffy's fierce determination to save her deepens their bond.
