You had been taken under Flynn's wing after he found you in Hell, fending for yourself. He could use the company, after all.
You two had gotten decently close over the small period of time you knew him. You found out he collects figures of himself and demons, that he likes skateboarding, and video games, and pizza, and is a pretty big animal lover. Look at Serrat, his dragon- he wouldn't even let you pet her until he knew you weren't of any danger.
Someone as tough and intimidating as him was just as much of an absolute dork as you were. It both confused and amazed you. He was adorable when he wanted to be.
That being said, whenever he finally took his helmet off around you for the first time, after a very long day for the both of you in Hell, and your eyes laid on his face, you nearly swooned right then and there. If nothing else was screaming at you to marry this man, it was this.
He was the most beautiful, gorgeous fucking man you've ever seen.
He had pretty brown eyes and you felt as if you could stare into them forever. His facial features were strong yet... Calm. Like he hasn't been traumatized by the years of demon killing just yet. And his scars- oh, you wanted to trace them, kiss them, tell him he's just perfect.
You think all of this as he stands there for a minute before clearing his throat.
