Has XO, Kitty Season 3 started production?

Season 3 of XO, Kitty has wrapped production, which Netflix revealed in July 2025.

 

Will there be new characters in the cast of XO, Kitty?

Yes, along with the announcement that production on Season 3 had wrapped, Netflix revealed that Sule Thelwell (Saint X), Soy Kim (Like a French Film, Sorry Not Sorry) and Christine Hwang (Law & Order: SVU) have joined the cast.

Thelwell will play Marius, who may or may not be the same Marius as Q’s (Anthony Keyvan) former roommate at KISS before Kitty moved in with him in Season 1. In Season 2, Q revealed that he and Marius had a romantic history.

“We did plant those seeds, and we may or may not see those seeds bloom,” Keyvan told Deadline on the red carpet for the Stranger Things Season 5 Volume 1 world premiere.

Keyvan will also soon appear in Just Picture It at Netflix alongside Millie Bobby Brown.

Kim will portray Yisoo, and Hwang will play Gigi.

Who else is in the cast of XO, Kitty?

Of course, returners include Cathcart, Minyeong Choi as Dae, Gia Kim as Yuri, Sang Heon Lee as Min Ho, Regan Aliyah as Juliana, Peter Thurnwald as Alex, Joshua Lee as Jin, Sasha Bhasin as Praveena, Michael K. Lee as Professor Lee, Philippe Lee as Mr. Moon, Jocelyn Shelfo as Madison, Han Bi Ryu as Eunice and Sunny Oh as Mihee. Hojo Shin, who plays Jiwon, has also been upped to a series regular.

 

What happened in Season 2 of XO, Kitty?

Season 2 watched Kitty discover more about her Korean heritage and meet her grandmother’s sister, who lives in Seoul, South Korea as a matchmaker. Kitty herself tried not to meddle as much in match-making, but she did give dating Praveena a shot. Unfortunately, her hidden feelings for Yuri eventually surfaced, causing much chaos for her friend group.

A talent competition sponsored by Min Ho’s father led Dae to get the chance to tour the world with Min Ho’s brother. Kitty last-minute asked Min Ho if she could go with him over the summer on tour with his father and brother. While her year of study abroad at KISS may be up, her scholarship got renewed so that she could stay longer. Q got into a summer track program at USC. Yuri and Julianna broke up after a letter Kitty wrote to Yuri revealed that they had kissed while Yuri and Julianna were dating.

What will XO, Kitty Season 3 be about?

Not many plot details have been released, but at the time of renewal, summer was the assumed setting for the beginning of Season 3. Actor Anthony Keyvan teased a “more mature take” from the cast, who play characters that are seniors in high school.

“It was a little bit different this season. We’re a little bit older. We’re dealing with a little bit more mature topics, I would say,” he told Deadline. “We’ve got some new cast members, which is always exciting, but it’s still the same old hijinks that the KISS students are getting into all the time. It was really great to be back.”

Who is behind the making of XO, Kitty?

Valentina Garza took over as showrunner for Season 3. Jessica O’Toole helmed Season 2.

Jenny Han executive produces with Matt Kaplam of ACE Entertainment. Awesomeness Studios also produces the show.
