Isuke could start as a very guarded character, but through interactions with Haruki, become more open and trusting. Haruki, on the other hand, might become more patient and understanding. For instance, if Isuke has trust issues due to past experiences, Haruki's kindness could slowly break down those walls, and Isuke would learn to be more vulnerable.
Isuke could become more expressive in terms of emotions. Initially, Isuke may keep their emotions bottled up, but Haruki's presence could change that. Haruki, in turn, could become more confident in their own abilities. As they support each other in different situations in the Akuma no Riddle universe, they both grow not only as individuals but also in their relationship. For example, when facing a powerful enemy, Isuke might show their concern for Haruki more openly, and Haruki could use that support to believe in themselves more and fight back more bravely.
Isuke might develop from being a lone wolf type to someone who values the relationship with Haruki. Maybe in the beginning, Isuke is solely focused on their own goals in Akuma no Riddle. But as they get to know Haruki, they start to consider Haruki's feelings and goals as well. Haruki could develop from being a bit naive to more street - smart as they face the harsh realities of the Akuma no Riddle world together with Isuke.
One possible plot could be that Isuke and Haruki start off as rivals in the dangerous world of Akuma no Riddle. They might be competing for a certain goal or mission. As they interact more, they gradually discover they have more in common than they thought. Their relationship then evolves from rivalry to friendship and perhaps something more romantic as they face various challenges together.
A plotline could be that Haruki gets into trouble and Isuke has to save her. This event could be the catalyst for their relationship to develop. Isuke, being brave and resourceful, manages to rescue Haruki from a dangerous situation, and in the aftermath, they start to see each other in a new light. It could also be that they are both outsiders in their school or group in the Akuma no Riddle setting, and they find solace in each other's company, leading to a romantic relationship.
Their relationship could be full of tension at first. Isuke might be more reserved and Haruki more outgoing, creating an interesting dynamic. As the story progresses, they might start to complement each other. For example, Isuke's calmness could balance Haruki's impulsiveness.
