The story begins with Winnie the Pooh searching for Christopher Robin but cannot find him so he goes to Piglet's house to ask Piglet if he had seen him. While talking with Piglet, he struggles to hide the arts and crafts supplies from Pooh but he is able to see what Piglet has been making. He finally admits that he is making a Valentine's Day card for Pooh. He and Piglet leave to find Christopher Robin. They, along with Rabbit, Tigger, Eeyore, and Gopher finally find him sitting near a log and is writing a card to someone called "Winifred". Not sure who that is, they go to ask Owl, who explains that a Winifred is a girl. He points out the reason while Christopher Robin is like this is because he's bitten by a smitten with love sickness. Pooh suggests finding a doctor but Owl shoots that idea down as the smitten is the love bug who can only cure. Tigger suggests finding another smitten to cure him. He sets up a bait with Piglet dressed as a gentleman with a bouquet of flowers who quickly moves off the hill that he is standing on when he realizes that it is an anthill. Pooh then notices a small firefly-like creature on his honey pot, which they assume that it is the smitten, which then flies off into the forest. They then chase after it but after a long search, they begin to worry over what it can do if it bites them. After Rabbit and Tigger describe unusual side effect that a smitten's bite can do in a song, they suddenly spot it and give chase. Pooh follows it down a path, leaving the others behind. Rabbit, Tigger, Gopher, and Eeyore, not sure which way to go, take different paths, leaving Piglet all alone.
