Me and my choice from Monster Prom: everyone's favorite eldritch waifu cutie-patootie, Zoe! In true Zoe-fashion, here's an AU for this:
Zoe is going to the woods for inspiration for new fanfics. The woods contain many terrors but none can phase a former deity of despair...unless they pop out of nowhere and startle her. She's so startled that her scream opens a portal to another dimension. When she realizes this, she (being a weeb) sees this as, "I pulled a Super Buu!" She doesn't realize this until long after she meets me, since she's in my dimension. To avoid culture shock, we agree not to let her see too many differences and too many humans. With just the two of us, we bond over our love of toons and anime, have healthy debates and...experiment. Who could say no to this beauty? Zoe can go back to her dimension anytime but chose to observe her new surroundings out of curiosity and me-oh-my, am I lucky I met her before she could meet someone better-looking. Can't wait to see her again.
