#10 has me stumped. It doesn't look to me like any of the stories listed in the Best Kiss category in the "Kerth 2015 Stories -Eligible By Theme" thread.
Ah, I see that now! Story #10 was one that someone alerted me to as having a first kiss, so I added it to the quiz after I had written the other 9 clues. I'll add it to the Eligible by Theme list after the quiz answers are revealed, just to keep it fair for everyone playing along.
