How does the 'fem Tsuna hates Iemitsu' fanfiction develop their relationship?

One possible reason could be that Iemitsu has been absent for much of Tsuna's life. In the story, this absence might have made Tsuna feel abandoned, leading to hatred. For example, Tsuna could have faced many difficulties growing up without a father figure, and all the pain and struggles could be directed towards Iemitsu.

Fem Tsuna might try to find distractions. She could focus on her hobbies or things she was good at before the abandonment. For example, if she was good at martial arts, she could train even harder to take her mind off the pain. And in the long run, this could also make her more confident and self - reliant. She may also start to write in a journal, documenting her feelings and thoughts. This can be a therapeutic way for her to deal with the abandonment and keep track of her growth during this difficult time.

Fem Tsuna could use her pain as fuel. She starts to practice her skills more vigorously. She might think that if her guardians don't want her, she'll become so strong that they'll regret their decision. So she spends her days training, getting better at combat or whatever abilities she has in the fanfiction.

In this fanfiction, perhaps there is some sort of danger that threatens Tsuna's class. Iemitsu arrives just in time to help. He uses his skills and knowledge to protect the class. Along the way, the students get to know him better and Tsuna has to deal with the complex relationship he has with his father while in the context of his school life.

In many fanfictions, it starts with Reborn being assigned to Tsuna and his possessiveness begins as a sense of duty. For example, he sees Tsuna as his to train and protect, so he doesn't want others interfering. As the story progresses, this possessiveness can turn into something more emotional. Maybe Tsuna starts to rely on Reborn's possessive protection, and they form a deeper bond.

Often, it starts with intense dislike. Snape is constantly critical of Harry in class, deducting points for the slightest mistakes. Harry, in turn, sees Snape as a bully. As the story progresses, there might be small moments of grudging respect, like when Harry realizes Snape's intelligence in potions, but the overall hatred remains for a long time.

Often, it starts with a small incident that sparks the hatred. For example, Percy might save a person or creature that Artemis was hunting, thinking he was doing the right thing, but from Artemis's perspective, he's interfering. Then, the relationship deteriorates as more misunderstandings pile up. Artemis might start to actively oppose Percy in his quests, using her own powers and influence against him.

Obviously, Tsuna and Iemitsu would be the main characters. Tsuna is the central figure in his class, and Iemitsu is his father. But also, some of Tsuna's classmates like Yamamoto, Gokudera and Kyoko could play important roles. They could react to Iemitsu's presence in different ways, adding more flavor to the story.

In these fanfictions, the relationship often starts with some form of mutual misunderstanding. For example, in many stories, Snape initially sees fem Harry as just another student, but as she shows her unique qualities, his view changes. Then there's the slow - burn aspect where they gradually realize their feelings for each other.

It might start with curiosity. Hiccup is intrigued by this new human - like Toothless. As they interact more, they could develop a bond based on mutual respect. For example, they might find they both have a love for flying, even if Toothless is now human and has to find new ways to experience it.
