Fate's manga / #unique(2)

Is it yuri cuz I hope it is since they both look girls and the plot looks interesting a vampire without fangs and doesn’t drink human blood ig? And a human masochist I think it fits well for them both

OMGGG THIS IS SO GOOOD ITS LIKE THE ONE WITH THE VILLAINESS HAS ONLY 24 HOURS TO ESCAPE THE DOOMED ENDING MANGA AND THIS IS JUST LIKE THAT ONE BUT WITH HER SISTER (bro I’m actually so invested but WHY DID HE BREAK OFF THE ENGAGEMENT?!!)
