I really like writing in first person POVs. I like having access to the characters’ full sensorium; I like being able to embody my MCs in my imagination. But I also need a justification for why this person is self-narrating, or why they would be narrating to the reader. Who are they telling their story too? Mac’s character concept was in part an excuse for a specific POV when I first started with him, though he’s a lot more than just that.
