Do you get both games or does your game upgrade orrr?

So I want the discount on Yakuza 0 Director's Cut, but I don't want both game's in my library because I'm a big achievement hunter, and I don't want to 100% the same game twice. I'd like to ask to anybody who get's the game through the discount, do you get both the Original and Director's Cut with the discount, does it upgrade your original copy, or does it take away the original copy and replaces it with the new one. Asking for a steam user btw. Also I'm aware the game comes out in a couple hours, this is asking for anybody who get's the game through the discount in a little bit.
