With Nikki always around, Andell is desperate for some alone time with her new boyfriend Lester, so she secretly arranges a blind date with Johnnie for Nikki, who is shocked at the idea of possibly cheating on Professor Oglevee, but Nikki's resistance gradually turns into attraction when she and Johnnie realize how much they have in common. Meanwhile, Mavis turns down Woody's marriage proposal, which sends him into a funk and causes him to move out---and in with Professor Oglevee.

When Nikki and Johnnie's relationship starts to get serious, Johnnie gets offered a job in New York, but instead of leaving Nikki behind, he asks her to marry him. Meanwhile, Kim, unable to graduate because she doesn't have enough credits, enlists Stevie's help to start her own design business instead.

While the plans are underway for Nikki's wedding to Johnnie, Professor Oglevee finally realizes he is in love with Nikki and is determined to stop the wedding, until Andell stops him first. Meanwhile, Stevie and T finally graduate from school.
