Fic recs where Erin is in Titan form and it’s erin/hange or eren/historia or eren/mikasa?

The series is so good😭😭😭 but there’s comparatively few fanfics. Are there any plot-heavy, in-character f/m fics where Erin’s attack titan is the main focus? Basically monster/girl fics. Yes I am a freak, thank you
