“That’s definitely what Kitty’s going through.”
Anna Cathcartisn’t the kid sister anymore.
Kitty began as the classic annoying and meddling little sister.

But now with a new spinoff series, both Kitty and Cathcart have grown up.
ENTERTAINMENT WEEKLY: What is your earliest memory of performing?
This is like little, little.

That is where it started.
From day one, I have loved this industry without even knowing it.
What was your first professional project?

I distinctly remember it being the most momentous day for me.
It meant so, so much.
It was so farfetched.

I did not think that would ever happen.
I had heard of the books, but I hadn’t read them then.
But I did read them when I was in the process of getting cast.

We didn’t know there was going to be a sequel.
Across those three films you’re the little sister, an endearing troublemaker.
It’s so surreal, honestly.

It’s a very different stage of her life.
That’s starting to shift a little bit and she’s starting to be uncertain for the first time.
Things feel like they’re all over the place, and she doesn’t really have it under control.

She’s now getting her own love story.
They’re a little bit more overwhelming when you’re in the center of it.
Kitty’s facing that.
Is it humbling for her?
Like, now she understands what Lara Jean was going through?
There’s a couple little references.
She’s like, “Oh my god, I’m turning into LJ.
What is happening?”
It’s like, “Oh, I get it now and I take it back.”
That’s happened to me too in real life with my older sister.
Now you’re doing it."
That’s how it goes.
That’s part of growing up.
Sometimes you have to experience it for yourself to get it and to fully understand it.
That’s definitely what Kitty’s going through.
How much of the show did you shoot on location in Korea?
It was such a special time in my life.
What was your favorite part of shooting there and what was the most challenging part of shooting there?
I loved that we got to see different parts of the city and shoot in different little locations.
Getting to be a tourist while working was fun.
But it was challenging being away from home for so long.
I grew a lot as an actor and as a person in my own life.
It’s very special to be a part of that for somebody.
It’s just a story about a girl who happens to be this race.
It’s not seen as a conflict or as an issue, which I love.
Do you feel like that’s been elevated further by the show’s Korean setting?
Our show is filled with a lot of diversity and a lot of Asian diversity.
Did you know any Korean going into it?
I did not know any, and I learned not as much as I should have.
There’s other little phrases that cast mates tried to teach me.
I would love to learn more.
What’s your favorite project you’ve done so far?
They’ve all been so special for different reasons.
Being such a fan made it something that was unparalleled.
It was a different jot down of special.
What’s a moment where you’ve felt like you’ve made it?
It blew my mind to be onSesame Street.
I lovedSesame Streetgrowing up.
I was like, “Oh, only super cool people get invited to go there.”
It’s an honor that I was chosen.
I’m still living in Vancouver and I’m going to university right now.
My life is happening at the same time.
Which helps me appreciate both sides.
