Don't Kiss Me, Little Devil (All Three Volumes)

Ruri is the most special being in Genkai Academy. She has no spiritual power, but she is favored by the arrogant demon king Saiya and the elf Shinru who has overturned the gods. And all kinds of strange things happened in Huanhai Academy due to the arrival of Saiya. It turned out that he was secretly looking for the heir of the King of Night, the pure-blood princess, to calm the conflict between the Night clan and the elves. Who is the real princess? If she could be identified with a kiss, Siye Prayer would not be the one he loved the most. He would rather endure a hundred years of loneliness than Liuli shed tears of sadness. Don't kiss me because you really love me; don't love me because you don't want to lose me. But I have been hopelessly conquered by you. Even if it costs blood, even if you are a bit bad, I will do whatever it takes to be with you.
