I always thought that Nick and Angie made a pretty cute couple while they lasted. Dysfunctional but cute.
According to vulture.com, Olivia Munn too were a fan of Nick and Jess. Read below:
Munn was noncommittal about whether her character would return, but it sounds like she would be upset if she were asked to return and endanger the developing romance. “I actually love Jess and Nick together,” she said. “So I think I was kind of secretly a fan mole inside the show pushing them together.” (source: vulture.com)
