Well, it's not very common. Fanfic usually focuses on more positive and legal relationship dynamics. The idea of an arranged marriage between a teacher and a student goes against the norms of a proper teacher - student relationship which is based on education and mentorship, not romantic or marital arrangements.
One challenge is the ethical aspect. Since teacher - student relationships are supposed to be professional, writing about a romantic or marital relationship can be seen as inappropriate. Another challenge is the power dynamic. The teacher has authority, and in an arranged marriage scenario, it can be hard to balance that power in a believable and non - exploitative way.
One possible scenario in a John Wick arranged marriage fanfic could be that John Wick is forced into an arranged marriage as part of some underworld deal. Maybe a powerful crime family wants to tie him to them through marriage to gain his skills and loyalty. His new partner in the arranged marriage might initially be scared of him because of his reputation, but as they spend time together, they start to understand each other and form an unexpected bond. John might be hesitant at first, but he realizes he has to protect this new person in his life as well.
Power struggle is a common theme. Since it's often a political arrangement, Loki and his partner usually have to navigate the power dynamics within the Asgardian or other fictional realms. For example, they might have to deal with Loki's family's expectations which are often tied to power and status.
Personal growth. Both Baekhyun and the main character often experience personal growth. They learn about themselves, their desires, and how to be in a relationship. In the process of dealing with the arranged marriage, they become more mature and understanding.
One popular Chanbaek arranged marriage fanfic is 'Destined Together'. It beautifully portrays their journey from reluctant partners to falling in love. The story has great character development and a sweet plot.
One great fanfic could be 'The Unexpected Bond in Narnia'. It explores how the characters adapt to an arranged marriage situation in a very believable way. The author does a wonderful job of integrating the magical elements of Narnia with the complex emotions that come with arranged marriages.
One common theme is the struggle against society's expectations. In these fanfics, the gay couple often has to deal with family or cultural norms that force the arranged marriage, and they have to find their own way within those constraints.
One common theme is the struggle between duty and love. In these fanfics, the characters are often in an arranged marriage which is a matter of family obligation, but then they start to develop real feelings for each other, creating a conflict between what they are supposed to do and what their hearts want.
One positive aspect could be that they understand each other's educational values deeply. For example, if the teacher has inspired the student in the classroom, this can translate into a strong bond in marriage. They may share a love for learning and intellectual growth. Also, they might have a unique connection based on the teacher's mentorship which can lead to a very supportive relationship in marriage.
