THE PLOT SO FAR: Orisno orders his young attendant, Cesario, to go win Olivia's love for him (Orsino), but Olivia is in mourning for her dead brother and "Cesario" is actually a cross-dressing girl named Viola, who is secretly in love with Orsino.
....you know, just your typical run-of-the-mill Shakespearean love triangle.
The "wooing" scene between Cesario and Olivia is one of my favorites. It's got some great poetry (see: the famous "willow cabin" speech) but, more importantly, is just plain charming. Olivia's flustration and panic at realizing she's falling in love with this page boy is simply adorable.
