Another plot could be a more emotional one. Maybe Rei is injured, and Takashi has to take care of her. This forces them to confront their feelings. Rei might be afraid that she's a burden, and Takashi has to reassure her. They could have heart - to - heart conversations about their past, their families that they've lost, and how they see their future together in this dangerous world. It could be a story of how their love grows out of shared trauma and the need to protect one another.
One possible plot line could be Rei and Takashi having to survive together in a post - apocalyptic world. They might face challenges like finding food and shelter while also dealing with their growing feelings for each other. For example, they could be in a situation where they are trapped in a building surrounded by zombies. They have to rely on each other's skills, Rei with her marksmanship and Takashi with his leadership, to get out alive. During this time, their relationship deepens as they see each other's strengths and weaknesses up close.

To write their character development well, first understand their starting points. Rei starts off as a strong - willed and somewhat cold girl, while Takashi is more of a regular guy thrust into a leadership role. As the story progresses, for Rei, show how her experiences soften her edges. For example, when she and Takashi save each other from zombies, she could start to open up more emotionally.
