I really don't get the Ecchi label, it's Smut. Good smut. So why the wrong label? And it matters. Ecchi is usually for the 'male' gaze, while smut has commonly been for the 'female' gaze. A lot more female centered nudity usually in Ecchi with really big (gratuitously so haha) breasts on female presenting characters.
Forgive me for the binary labels my non gender conforming siblings 🙏🏽
