In Season 2 of XO, Kitty, teen matchmaker Kitty Song Covey came back to Seoul for a new semester at KISS following quite a dramatic ending of the first half of her study abroad scholarship program. Single for the first time in a long time, she attempted a fresh start with the goals of no more meddling and no more drama as well as some casual dating — outside of the friend group. A letter from her mother's past sets her on another wild journey of family history sleuthing, and new faces at KISS shift the trajectory of not only romantic relationships, but possibly careers.
