33 parts Complete Airyn is great at making poor life choices, but she has to admit bringing home an injured, sword-wielding stranger she met in the middle of the night in a park is probably the peak of stupidity. Then she finds herself offering to help dodge the police and show him around town.
The more time she spends with him, the more she thinks he's off his meds, or she's the victim of a television prank show. There's no such thing as magic, and he can't really be a knight in shining armor, but for once her life isn't boring.
When the portal back to his world stands open before her, she can't let him disappear from her life. She takes his hand and follows him to his world, swearing to help him finish his quest and save a princess. Without trains, showers, or coffee.
