Your chapets aren't long enough to make a chapter, your concept is lacking, and in general, this story isn't worth the time it took to appear on my screen.
I agree that Severus is a complex character with much to offer, however, you fail to convey anything but an insipid disregard for what literature looks like.
And btw, 'Sevvy', is a retarded nickname. Please never use it again. Ever.
