It gets -1 enjoyment points for me because I really do not like arranged marriages (even yuri ones). Other then that super fluffy as usual and just like everybody else I hope it does not become a love triangle (a romantic three way relationship would be fine I guess)
having mixed feeling about the fiancé. now she doesn't seem as warm as how Chiru describes her from her flashback.
also i guess this gonna be one sided love? Kayo, the type to always protect her Ojou-sama because of duty, but actually has come to adore and love her :3
For the sake of discussion, the setting looks very much like late 19th, early 20th century Japan, just with everyone having two sets of ears and girls being legally allowed to love girls, if only recently. This probably means that unless magic is introduced, no same-sex reproduction is possible.
So why would a marriage be arranged between two girls of families that has so little in common? Their residences are far apart, their social standing too. This probably won't be explained, but it might be a conspiracy brought on by a third party, with the aim of cutting off those two families' lines, by blackmailing the fathers?
Another possibility is that author didn't actually thought it through and simply used the elements s/he likes to write about: yuri, marriages, and animal ears.
