I've given up on the harem. After those two rejections, I really don't care who wins anymore. Though I still wish Hayate would come back to A-tan again. Even Nagi is fine, she's turning into a good character after the doujinshi arc. Nishizawa will lose obviously and I lost hope for Hina cause she's still stuck in square one for the past 400 chapters!
So the people I'm rooting for are Nagi and A-tan.
