I wrote the novel for fun, since I had an interesting idea that I wanted to try. I'm normally pretty busy (I happened to be taking a week off during WPC), so I ended up writing pretty much all 22 chapters in that week.
When I got the notification for the gold-tier contract offer, I told the contact person that I didn't intend to sign and was told that I would forfeit my entry as a result. Signing the contract is required to end up on the winner's list and to get any of the prizes. Ever since the WPC prizes had been changed to including a contract, they no longer acknowledge anyone who doesn't sign.
Besides, I have no use for a contract. I've refused them for my other novel too. The money to time ratio is just too low for me to care, since my normal job makes more in one day than MGS in one month.
Therefore, enjoy my fun writings for free!
