Someone's Got Cow Eyes for Merlin

Merlin receives a love note from a secret admirer and immediately thinks it's a joke. As honestly, what respectable person would use such a terrible rhyming scheme? Canon Era AU, Fluff/Crack/tiny dash of angst. Merlin/Tall, dark, handsome Drui- stranger (lol 'tis obvious who it is), and Gwen/Lancelot.
