Gouhou Yuri Fuufu Hon(2014)

In a country far far away, the inhabitants are very similar to humans but the two distinct differences are their animal ears and their acceptance of same-sex marriage.

25-year-old Haru never had time to think of romance once her father died suddenly. Now that she is the last of her mother's unwed daughters, her uncle proposes an arranged marriage between her and a beautiful older woman. Haru accepts and the two are rushed through the ceremony. Now, they find themselves married to a stranger and adjusting to a new life as a married couple. Becoming closer, learning about one another, and falling in love is what this manga centers on.
