Usually with genderspecials it's easy to realize what they actually want beneath all that newspeak, but this one... I've read this comic a couple of times, but i still have no idea. She dislikes her breasts but not enough to mutilate them (thankfully). She wants to be beefier, but partially because she doesn't want to look too feminine while wearing a dress. But at the same time she seemingly is fine with being feminine, because she doesn't want to look masculine or so androgynous that it would hurt her dating prospects. So basically this clip.

My guess is, this woman has some general body image/anxiety issues, and under different circumstances she would've been caught up in some other harmful fad like extreme dieting.
