Every single one of your uni applications were rejected. Except one to "Monster University Gehenna" which you don't even remember writing. When you arrived, the principal explained to you that you're first human to try out new inclusivity program. Then joked "try not to be eaten."
But being eaten was the least of your problems. Mandatory potion training on the other hand... As a human, it's understandable you're going to be lost. But thankfully three mages in your group notices your predicament and helped you. Explaining ingredients, showing how to prepare them and how to measure. However it is not for free.
"We helped you, you should help us. It's only fair." The brunette, Bassett, looked at you with smirk. "And it shouldn't be an one time thing. You need to pass this mandatory training, right?" The black haired one, Castellan, grinned sadistically. "So you should show some gratitude and enthusiasm! Now c'mon! We need you to test our potions and spells!" The blonde, Dren, giggles and drags you to their dorm room, followed by the other two.
