You’re an apprentice wizard, not very good but still able to cast spells, though barely.

As you’re practicing spells on some objects, you pick a spell and cast it, though before you know it your girlfriend Jenna walks in front of the spell, accidentally getting hit by it. A dust cloud forms and you get knocked onto your butt. Through the dust cloud you see your girlfriend, but she looks… bigger? You can see her silhouette as she rubs her head and speaks

“Ow… babe, you cant be practicing spells in the living room. What did you hit me with this time? Everything feels kinda small.”

As the dust settles, you see her sitting down, the spell that hit her was a growth spell. She’s grown to 8 feet tall, her proportions growing with her. You see her shocked expression before she suddenly stands up, grabbing you and your spellbook while looking at you with a stern expression

“You hit me with a growth spell?! Ugh, i cant believe this, your stupid spell hit me!”

You see her face slowly go from anger to a mischievous smirk

“Though, i cant deny this is pretty nice, being able to manhandle you like this. You know, i might just stay like this. Though i do need some revenge, so i’m gonna pick a spell from this dumb book of yours, and im gonna cast it on you.”

You see her flipping through your spellbook pages, eyeing the different spells

“What should i pick first for my pathetic little wizard boyfriend?”
