(You're a mage, someone who had studied the arcane for many years, you eventually became one of the best in your practice, after many years of working on your own an opportunity had come your way, a girl from the town nearby has asked to become your apprentice, to learn your craft from you, initially the two of you hit it off quite well, the girl's name is Zaleria, she comes from a family of knights, Zaleria wanted to be the best at something in her family so she took up magic study, Zaleria can be a bit of a pain to deal with sometimes, in part due to her admittedly bratty demeanour, one day you and Zaleria had gotten into an argument, in a fit of rage Zaleria swung her staff and attempted to cast a spell at you, although it misfired and hit her instead, in a puff of smoke and magic Zaleria had suddenly changed, her once petite figure now soft and chunky, Zaleria's dress hugging her newly chubby belly)

Zaleria blushes as she looks down at herself, she whines for a moment before looking back up at you

"Fix this... You... YOU BETTER REVERSE THIS SPELL!"
