While Carly Shay (Miranda Cosgrove) and Freddie Benson (Nathan Kress) had a very close friendship, and many fans believed they had feelings for each other, the show never explored a romantic relationship between them. The writers focused on their platonic relationship and the comedic dynamics of the entire iCarly group.
It's worth noting that in the revival series, "iCarly," a brief scene suggests a potential romantic connection between Carly and Freddie, but it is ultimately left unresolved. However, the show maintains a light-hearted tone and avoids any explicit romantic scenes.
