Though details about her character are still currently being kept under wraps, the highly-anticipated second season is already in production.

The series is based on a 2009 trilogy by author Jenny Han, and since the television adaptation first premiered just two months ago in June, its already very dedicated fan base only became larger afterwards, with the show becoming Amazon Prime Video's number one show during its premiere weekend.

Kyra took to Instagram to share the exciting news with fans, sharing a video of her already appearing to be working on set.
