How the This Is Us Couples Achieved Their Incredible Chemistry

Of course, this amazing dynamic doesn’t stop with the fan-favorite couples, as Justin Hartley revealed that his castmates really do feel like his siblings. “As the years go by, you start to develop a love for each person,” he gushed. “And I can tell you that I love Sterling like a brother. I love Chrissy like a sister. I love Milo like a brother—not like a dad—and I love Mandy like a sister. We’re a family.”

Continuing on this point, Justin added, “That’s the greatest thing you can take away from a show like this, you can have these lifelong friendships and bonds.”

Love for the Pearsons and the actors who play them will surely keep us going even when the series ends. For more from E! News’ farewell to the family, click here. 

This Is Us’ final season kicks off Tuesday, Jan. 4, at 9 p.m. ET on NBC.
