"How to Return to the Right Path in Four-Corners Relationship": Fantasy Romance-A novel from a different world. Watch a cute girl tear apart the four corners with her bare hands and walk towards the peak of life with an indifferent, studious male god! I hope you like this fairy's recommendation. Muah ~😗

One characteristic is the emotional tension. For example, in many love triangle novels, the protagonist is constantly torn between two suitors. This creates a lot of internal conflict and keeps the reader engaged as they wonder who the protagonist will ultimately choose.

One classic is 'Inuyasha'. There is a love triangle between Inuyasha, Kagome and Kikyo. Inuyasha has a past with Kikyo, but as the story progresses, he also develops strong feelings for Kagome. Another is 'Fruits Basket'. Kyo, Yuki and Tohru form a love triangle. Yuki has a gentle affection for Tohru, while Kyo has a more passionate and complex relationship with her.

Jealousy is a common theme. For example, in many love triangle anime, when one character sees the person they like getting close to the other person in the triangle, they get jealous. It can lead to arguments and emotional outbursts.

Another popular choice is 'Toradora!'. The story involves a compelling love triangle that evolves throughout the series. The character development and emotional depth make it stand out.

One popular example is 'Toradora!' where the relationships between Ryuuji, Taiga, and Minori create a complex love triangle that keeps viewers engaged.

Well, usually it's about jealousy, competition for affection, and the struggle to make a choice.

I'm not sure which one you're referring to because the name might refer to a different anime or work. If you can provide more information such as the title of the work, the author or the platform, I will be happy to help you confirm the answer.
