Help I'm searching for an Ao3 fanfic i read a few month ago ;-;

In this fic merlin thought Arthur and the knights didn't appreciate him enough and decided to transform into a woman, "Melody" (a cousin of merlin if i remember), to see how they actually saw him and what they think of him.

I think Gwen helped him but not sure.

I really want to read it again bu impossible to find it again !
