I approve of this comment, even if some of the critisims felt unnecessarily harsh here and there.
Regardless, as I agree with pretty much everything there, I'll add that, the relationship dom/sub with Hana and Kaisa was great, and I'm always sad to see it's been completely forgotten as time went on.
Seeing Kaisa starting to obsess over the idea of being Hana's was great, and I really thought there'd be an option to let Hana have her like 90% at some point in the story.
