"All the princes say the same thing, they must really like Jeno, they only look hard to search for you" Unlike the well-known tale of the princess who is trapped in the forest and the fire breathing dragon, Princess Mikaela and dragon Jeno don't have a typical kidnapper and hostage relationship, but a butler? Guard? A never-aging friend of Mikaela's mother, Hildian? Whichever side you take, he is much better than the princes that wake Mikaela up in the morning, until one day, Jeno gets poisoned by a prince, loses consciousness and his body starts heating up!
Note: The webtoon was released as R15, it's not R19 like the novel.
