Hello! Oh so sorry, my bad, I didn't know it was already used. It was a mystery key I won somewhere, and it was already for this game which I already own. Don't worry, I will compensate with a new steam key soon. Apologies again for the dupe.

Hello again! Is it ok if I add you on steam? I can gift you the game instead, as there is no other option on steam (won't let the user who wants to buy it but already has it in their inventory buy it again to trade), and I would prefer a direct gifting method, instead of buying a key on Humble Bundle, or other sites like the sort. Of course, once the process is complete, you can remove me from your friends list XD
