To develop their relationship, it's important to show their internal struggles. Izuku may be conflicted about his feelings for Tsuyu because it goes against his villainous image. Tsuyu, on the other hand, may struggle with the idea of befriending a villain. By exploring these internal battles, their relationship can become more complex and interesting.
First, start with their initial encounters which are full of conflict since Izuku is a villain and Tsuyu is a hero. As they cross paths more often, they could gradually start to have conversations that make them realize they are not so different. For example, they might both have the same goal of protecting the weak, just with different methods.
You can also introduce external factors that force them to rely on each other. Maybe they are both targeted by a bigger villain or a corrupt system. Through shared hardships, their relationship can develop. Tsuyu might see the good in Izuku that he has buried deep inside, and Izuku might start to respect Tsuyu's strength and determination.
Their relationship could develop uniquely if Izuku starts teaching Tsuyu about things he's learned from his non - quirk - based studies, like advanced first - aid or survival skills. Tsuyu, in turn, can introduce Izuku to her amphibious friends and the unique world she comes from. This exchange of different knowledge and experiences can bring them closer in a very special way.
A more complex plot could involve a time - traveling aspect. Villain Izuku from the future travels back in time and meets a younger Tsuyu. He tries to manipulate events to his advantage, but Tsuyu's kind nature starts to change him. This could lead to a whole new timeline where Izuku's path to villainy is altered.
In many fanfictions, Izuku's character development often focuses on his confidence. Tsuyu's presence can be a stabilizing force for him. For example, when he hesitates during a fight, Tsuyu's straightforward and practical nature might encourage him to act. As for Tsuyu, she may develop her leadership skills. If she and Izuku are in a team - up situation frequently, she might learn to be more assertive from Izuku's determination.
The relationship could develop slowly. Deku would likely admire Tsuyu from afar at the beginning. Then, they could be involved in group activities where they start to work together more closely. Deku would notice Tsuyu's kindness towards others and her determination. Tsuyu, in turn, would see Deku's growth and his unwavering spirit. As they get to know each other better, their relationship would progress from acquaintance to friendship and then to something more romantic.
Well, at first, their relationship in the fanfiction could be a bit awkward as they transition from friends to spouses. But as time goes on, they start to learn more about each other's habits and preferences. Mina might introduce Izuku to new forms of entertainment, like some really cool dance parties. Izuku, on the other hand, would share his love for hero lore with Mina. They would also start to take on more responsibilities together, like mentoring young heroes - in - training. This would not only bring them closer but also make their relationship more complex and fulfilling.
One of the things that make Izuku and Tsuyu's relationship in fluff fanfics so adorable is their contrasting personalities. Izuku is often nervous and over - enthusiastic, while Tsuyu is calm and level - headed. For example, in many fanfics, Izuku might be freaking out about an upcoming exam or mission, and Tsuyu will be there to soothe him with her simple yet wise words. Their interactions are filled with a lot of cute moments like this.
One interesting aspect could be their unique relationship dynamics in fanfiction. For example, a story might explore how Izuku's determination and Tsuyu's calm nature interact in different situations, like during a difficult mission. Maybe they have to rely on each other's strengths and in the process, their bond deepens.
In the fanfiction, their relationship could start with a bit of competition. Both are ambitious to be heroes. However, they soon realize that they can achieve more by working together. As kids, they might compete in small challenges like who can run faster or jump higher using their quirks (or in Izuku's case, his physical training). This healthy competition could fuel their growth and transform into a deep - rooted friendship that withstands all the difficulties they face later in their hero careers.
One of the best aspects is their mutual respect. Izuku respects Tsuyu's strength and her unique way of thinking. Tsuyu, in turn, respects Izuku's determination and his growth as a hero - in - training. In non - lemon fanfics, this respect is often shown through their interactions during training sessions or when they are on missions together.
Their relationship could develop slowly. At first, Toga might be curious about Izuku because he's so different from the others she's known. Izuku would be cautious but also see that Toga is more than just her villainous reputation. They might start by having small conversations, gradually learning about each other's hopes and fears. As they spend more time together, they could develop a deep bond. Izuku might inspire Toga to be a better person, and Toga could give Izuku the confidence he needs in a world that doesn't believe in the quirkless.
