I'm not entirely sure as the title 'atas nama cinta novel' is rather ambiguous. It could potentially be about a story of love that is named or dedicated in the name of love in the context of a novel.
Some quotes about love from novels could be 'Love is patient, love is kind' from religious texts which are often quoted in novels with a spiritual or moral undertone. Another might be from 'Pride and Prejudice' where Mr. Darcy says 'I have been a selfish being all my life, in practice, though not in principle'. This shows his journey in love and self - discovery.
I'm not sure specifically as there could be many novels with this title or related to this phrase. It might be about a story where the protagonist is transported to another world ('isekai' means another world in Japanese), perhaps with adventures, magic, and new characters.
Writing fanfic that involves sexual content is generally not appropriate as it can violate ethical and moral boundaries, and may also go against the terms of use of certain platforms. Moreover, it objectifies the characters in an improper way.
Take the character Heathcliff from 'Wuthering Heights'. His quotes about his love for Catherine are full of passion and a sense of possession. His statements like 'I cannot live without my life! I cannot live without my soul!' show how his love defines him and makes him a complex and tortured character. These quotes not only show his love but also his extreme personality.
Another theme is perseverance. The lovers usually face numerous obstacles, such as misunderstandings, family opposition, or social constraints. But they keep on fighting for their relationship, which shows great perseverance. For example, in many such novels, the couple might be from different social classes, and society looks down on their relationship. But they still strive to be together.
The 'isekai kara kita yuusha novel' likely tells a story full of fantasy elements. The hero coming from another world is a common trope in isekai stories. He could be summoned there by some magic or accident. Once in this new world, he may have to adapt to different cultures, magic systems, and races. His experiences would form the core of the story, which might include battles against powerful foes, exploring unknown lands, and uncovering the secrets of this new world.
One common theme is friendship development. Since kita and bocchi are often characters in a story, their friendship might be explored in depth, showing how they get to know each other better over time.
