Well, a common theme is the exploration of their individual pasts. Maybe Freed has some secrets from his past that Mirajane helps him come to terms with, or vice versa. Romance is also a big one.

They could be in a situation where they have to prove their loyalty to each other and the Fairy Tail guild.
Some fanfictions might focus on the theme of self - discovery.

They both are part of the Fairy Tail family, and fanfictions can show how they support and care for each other like family members, but with a hint of something more.
A plot could involve a magic competition in the Fairy Tail guild. Mirajane and Freed both enter. Mirajane wants to show off her new transformation magic, and Freed aims to prove the power of his rune magic. As they compete, they start to learn from each other.
