From Aerandria Scans:

A high priestess' rendezvous with an outwardly ambivalent ruler of a country with an unknown power. Tasked with ascertaining the legitimacy of this mysterious power, our heroine high priestess sneaks in the ruler's palace to peek around. Unbeknownst to her there is much more than meets the eye to this ruler.

After Kokoro’s parents die in a car accident, she remains the only successor of the Yukimine family and therefore the entire wealth also belongs to her. Being still young and inexperienced, her grandfather persuades her into choosing a fiance from a list of candidates. On top of all this, Kokoro can’t see the candidates’ faces because ever since her parent’s accident she’s seeing people’s faces as animals and is unable to tell who’s who. It looks like she’s going to have to choose based on their actions (and maybe their hearts) witch it’s rather hard to do considering that they are all suspected to have had a good reason to plan her parent’s accident. Put all that into a Christmas-like atmosphere and you get a magical romance set in the holy night of Christmas Eve.

From Cidsa:

A series of one-shots set in a world that seems to be mostly like ours... but with centaurs. The stories are all about human/centaur interaction, and most have a slice of life feel to them. Some are sweet and innocent, some a little sad, a couple are explicit. Featuring est em's typical deceptively simple, masterful composition and writing.
