Another plot could involve Tamaki getting injured during a fight. Shinra then takes it upon himself to take care of her. As he nurses her back to health, they have a lot of time to talk and get to know each other on a more personal level. This could lead to them realizing that they have a lot more in common than they initially thought, and their relationship could grow from there.
In a fanfic, their relationship could also develop through moments of vulnerability. Let's say Shinra has a nightmare about his past and Tamaki is there to comfort him. Or Tamaki has a moment of self - doubt about her abilities, and Shinra gives her an encouraging speech. These moments of showing their true selves and being there for each other can deepen their connection. It's about creating situations where they can be honest with each other and build an emotional bond.
Often, there are plotlines where they have to deal with misunderstandings between them. For instance, Arthur might misinterpret Shinra's actions, leading to a rift in their relationship that they then have to repair. There are also plotlines where they are pitted against a common enemy that forces them to work closely together and understand each other better, strengthening their bond.
