While staying with Sunset in the human world for a weekend, Princess Twilight falls ill. Now it’s up to Sunset to take care of her. Sunlight romance if you squint maybe, but also a reference to Sci-Twi being Sunset's girlfriend.

Somewhat of a sequel to Love Cures All as it does reference Sci-Twi throwing up on the carpet from that story, but you don't need to read that one to get this.
