Mein Ritter - Watashi no Kishi

Andrea Marcos is a young man looking for someone to translate a mysterious letter left to him by his late mother. His search leads him to viscount Theodore, a young, prodigious but hot-tempered and grouchy young man, fluent in 8 languages and a popular author of illusionary stories. To make things more interesting, not only does the viscount not believe in anything paranormal but the letter was apparently delivered to Andrea by fairies...?!
