Lucy could give Aquarius more freedom outside of the key. Let her experience the human world more often. They could go on adventures that are not related to Fairy Tail's main quests, just the two of them. This would allow them to get to know each other on a more personal level. Aquarius could also teach Lucy more about celestial magic and its deeper secrets, which would bring them closer as they explore this knowledge together.
Often, you'll see the theme of trust. Since Aquarius can be a bit prickly and Lucy is so open - hearted, building trust between them can be a great plot point. Also, adventure is a theme. They might go on some wild adventures together, facing challenges that test their bond.
I'm sorry, I don't know the exact plot as I haven't read it. It could be about Lucy going through some kind of loss or struggle related to Aquarius. Maybe Aquarius disappears or is in some kind of danger, and Lucy has to deal with the consequences.

One possible plot twist could be that Lucy doesn't immediately master the Aquarius power. Instead, it starts to have a negative impact on her at first. For example, it might make her lose control of her other magic abilities. Another plot twist could be that the source of the Aquarius power is somehow corrupted, and Lucy has to find a way to purify it while still being able to use it. Or perhaps there's a hidden side to the Aquarius power that only reveals itself in a moment of extreme danger, like it gives her the ability to communicate with an ancient and powerful water spirit that she has to convince to help her save her friends.
One idea could be that Aquarius gets trapped in a different dimension, and Lucy has to go on a dangerous quest to rescue her. She might have to team up with some unexpected allies from Fairy Tail.

They initially don't believe it but as events unfold, they realize they have to work as a team to save the world.
