The stars of Hulu’sWe Were the Lucky Ones were tasked with telling the true story of a Polish-Jewish family’s fight to survive World War II, quite an emotional and heartbreaking story to tell. Luckily for Joey King and Sam Woolf, who play love interests Halina and Adam, they had each other to lean on.

Talking to SheKnows about their first scene together, in which they’re seen kissing in a park in episode one, Woolf admits he was immediately impressed by King. “I was super nervous and then the moment we started it was like, ‘Oh I just have to look at this person and react to them and fall in love with them,'” Woolf tells SheKnows, adding “It was sort of the easiest thing in the world.”
