Nah. A lot of women/girls with a tough or boyish persona often have a softer side that they normally don't show other people. So I'd buy it in this case (It's not as bad as Troi being into Westerns).that time tom caught b'elanna with a romance novel. shocking from her usual serious and ferocious attitude.
That always reminded me of that strict butler character in Howard's End who was caught reading romance novels. Sometimes the hard cases are protecting a soft side.
