I must confess that that Snape!Mpreg is a guilty pleasure of mine, so I try to work it in whenever I can. *grins*
About Harry being sentimental--I don't see him that way most of the time. He's hot-headed, broody, arrogant, and a whole host of other things, but not sentimental. He doesn't deal well with the tender emotions, no matter what JKR tries to cram down our throat.
Anyway, I'm glad that you liked the story and that you want to read more of my writing. It makes me happy.
