Chitose is also 100% NOT interested in dating Ayano. She WOULD however love to see her with Kyoko. She wouldnt love to fantasize about them together if she wanted to date her! Also, you left out Chitose's sister- THAT is who you'd pair her up with if anyone.
Don't forget Chizuru has her two friends who seem really into her, she could form a threesome with them or Chizuru could date one whilst Chitose gets the other.
