Boy of the Female Wolf: Tomboy < BotFW < FtM

On the heels of one gender bender I present to you another. The description tries to be all mysterious, but the story pretty much gives away the gender of the main character in the first chapter. So no big spoilers (I hope) when I tell ya it’s a girl.
This is a rather odd story. I guess I haven’t had much time with this genre but this is the first story where I honestly wouldn’t have been able to tell what gender the main character is if I hadn’t been told. Usually in these things the main character is forced into taking on the role of another gender for one reason or another. This is honestly the first I’ve read where the main character (not a side character) does it just for the heck of it.
And honestly the ambiguous nature of our protagonist is what drives the story. The main character isn’t 100% hiding the fact that she is a girl. It’s more like she isn’t correcting anyone when they take the natural assumption that she’s a he. Even the romance element that seems to be the main focus felt a lot more like Yaoi than a heterosexual relationship.
But I liked this story because Eun-Soo was a guy when she felt like it (which was always) and just a little bit of a girl, when things got heavy (Very, very, very little bit).
Well, it’s interesting. I still don’t know most of the names. I know one…and that’s the one I typed out (Korean names are hard D=). There is no anime as of yet, but the manga is up to volume 10.
(P.S. Eun-Soo is the one with green hair just tossing it out there)
