Complete story — includes the ending
It's Valentine's Day at the office. Michael is attracted to a woman who loses a glove at a Valentine's blood drive; Cinderella -like, he tries to track her down. The staff share their worst break-up stories and band together to host a "Lonely Hearts Party" where they root for Michael's would-be romance. Jim and Pam have lunch with Phyllis and Bob Vance, which turns awkward when they hear the Vances having sex in the bathroom.
