From Baka-Updates: Sena is a high school girl who was on a school trip when she met a certain young man. While she was staring at him, for some reason, the young man suddenly kissed her!? The young man's name is Yuzuki, and he is apparently a crow-billed Tengu who has been cursed and in order to lift the curse, he has to marry a human! Yuzuki then declares, "Sena, starting from today, you are now my bride."
