Is It Odd That I Became an Adventurer Even If I Graduated From the Witchcraft Institute?

Synopsis:

William Glenford is capable of landing any job because he graduated from the prestigious Witchcraft Institute at the top of his class. William has fortune, fame, and prestige at his feet, but he only dreams of one thing: adventures. They immediately begin to notice that he is grossly overqualified for his role and rank, and that this mage may not be a mere "mage," but a full-fledged, national-level wizard. He finds companions in a typical guild with an up-and-coming party of girls, including a cleric, a martial artist, and a beastman catgirl. Will William acclimate to his party, or will the young ladies at any point expect to make up for lost time to him? Will the girls accept him, despite the fact that he is vastly superior to them, or will he always be the big fish in the small pond?
