What are some interesting ideas for an 'Attack on Titan OC Harem Fanfiction'?

A male OC in an Attack on Titan fanfiction could be a double agent. He pretends to be on the side of the Titans while actually working for the Survey Corps.

Another interesting idea is a male OC who is a healer. In a world full of Titan attacks, most of the focus is on combat, but a healer OC could bring a new dimension to the story.

Perhaps the friendly titan is a protector of a certain area outside the walls that the humans have not explored much. The story could be about the Survey Corps making an alliance with this titan.

This could lead to a whole new understanding of the titan world and how they can co - exist with the friendly ones.
