Hartley, 45, spoke to PEOPLE at Tuesday’s premiere for Netflix’sSenior Year, teasing what’s next for the actor after the NBC hit show’s May 24 series finale.

After playing Kevin Pearson for six seasons, Hartley admitted he’s been mentally steeling himself for the show’s conclusion for a while now.

“I’ve been kind of preparing for this for years and logging all those times and sort of going, ‘Okay, this is a moment that I should remember let me burn this into my brain.’ And I’ve been doing that for so long that it’s kind of just really sweet,” he told PEOPLE.

“The ending was really sweet and wonderful and exactly how we wanted to do it,” he continued. “And no one forced us out. And so all of those things, I think play a part in not being as sad as people might assume you would be.”
