Witch's Vampire Classmate

Olina is a poor little witch who was rescued by a passing male elf classmate when she was bullied and cornered. The male classmate has superb magic power, blond hair and blue eyes. He was praised by others and he sharpened a pair of small fangs in the dark. The day Olina grew up to be a qualified witch, she discovered that the sunny elf next to her was clearly a hidden vampire!
