i acutally like the koko x myako ship i don´t think the myako x hana works at all
Same here, though Miyako might be willing to go the Yuzumori/Ginza route. i think her and Hana understand each other better nowadays.
Because I like pairing up characters, I think Kouko x Miyako does a lot of good.
It keeps Miyako from romantically obsessing on Hana (which at least for now is a good thing).
It helps force Hinata the sis-con to give up on her sister.
That gives Noah a chance with Hinata.
If just one person turning around breaks the whole love dodecahedron, that's often the best outcome.
Also, Kouko loves Miyako for herself, regardless of what she finds out about her, and despite her fixation on Hana, Miyako is such a nice character she deserves that. Plus even if they dated, Miyako would still make treats for the kids, so Hana would be fine.
