I see someone said it above, and it was something I also thought of: possibly Kuro has a Mafia power role and so decided to let Honey die instead. But that still wouldn't explain why they wouldn't vote for Honey as to not be tied. Doesn't it look more suspicious to not vote at all than to vote for Honey?

Unless of course he's lynchproof. I dunno, guys, I'm just talking what I'm thinking.
