Fluttershy is shopping with Rarity in the Canterlot Market when she sees what she calls "the most beautiful mare in Canterlot" walking by and said mare offers her a smile before continuing on her way. When Rarity hears Fluttershy's description of her, she decides to ask her friend Fancypants for help in finding and meeting the mare.
Fleur de Lis is heading to her agent's office, after being called in at the last minute to review some contracts, when she sees a cute yellow Pegasus looking at her in the market. Not wanting to be late, and not sure how Canterlot would respond to her dating another mare, she offers the mare a smile and continues on her way. The next day her brother comes by, and after talking with her about a business proposition, tells her that there's a mare, a friend of Rarity's, that saw her the day before and now wants to meet her.
A Flutter de Lis story, told from both Fluttershy's and Fleur's perspective, inspired by a picture and a few stories I've read using a similar concept.
