"We love each other in a very friendship way and there's real love there, but I think in an alternate universe - I can't even imagine - if we would've dated, I think it would've ruined the movies," Condor, who stars as Lara Jean Song Covey in the "TATB" trilogy, told Entertainment Tonight.
Centineo, who plays jock Peter Kavinsky, shared similar comments, saying that "it's important to have a high level of professionalism when going to work."
"I think beyond that it was very natural for Lana and I to settle into a place of friendship," he said. "We've had each other's back from the very first day that we met."
Condor and Centineo became breakout stars following the release of "TATB" in August 2018. The popularity of the film led to two more installments, also based on Jenny Han's book series of the same name.
Their natural chemistry throughout the franchise let fans ship them in real life, hoping they'd become a real-life couple, even though Condor has been dating actor-singer Anthony De La Torre since 2015.
"I could not even imagine working in a romantic setting with an ex," she said. "That sounds like an actual nightmare."

She continued: "It's a literal miracle that all of us still feel so much love towards each other because when you spend that much time with each other and your whole worlds are changing together a lot could happen."
