I am always and forever a Yoshiko x Hanamaru diehard fan, but I am also very into:
-DiaRiko
-YouChika
-ShizuKasu
-YuuPomu
-YuuMia
-SetsuShio
-SetsuVice
-LanEmma
-AiRina
-KuuRen
-ChisaKanon
-NicoPana

For other pairings I can see the vision/enjoy them, with the exception of NicoMaki, ChikaRiko, YohaRiko, MiaRina, and SumiKeke, I don't really have much to say on them (at least anything positive), so I keep my mouth shut on them
