As XO, Kitty approaches its midpoint with Episode 5, "TBH," the series delves into the rich tapestry of Korean culture and the complexities of family bonds. The episode centers around Chuseok, a holiday akin to Korean Thanksgiving, which serves as a backdrop for a series of revelations and heartfelt moments.
The episode opens with Kitty's ambitious plan to host a Chuseok celebration for expats at KISS, an event that quickly gains momentum and becomes a school-wide affair. This initiative not only showcases Kitty's capacity to bring people together but also sets the stage for her to glean information from Alex, whom she suspects might be her long-lost brother.

Kitty's preparations for the feast are endearingly chaotic, made all the more manageable by Min Ho's unexpected offer to help. Their shopping trip and subsequent cooking session provide a sweet interlude, allowing for a deepening of their friendship. Min Ho's assistance proves invaluable as the Chuseok celebration draws an unprecedented turnout, marking a significant moment in KISS history.
The Chuseok dinner is a resounding success, with Kitty's signature mashed potatoes stealing the show. However, the evening's true purpose—Kitty's quest to confirm her suspicions about Alex—remains elusive. Alex begins to share his reasons for coming to KISS, but his revelation is cut short, leaving Kitty hanging on the edge of a mystery.
The episode takes a poignant turn with an awkward conversation between Alex and Professor Lee, the latter of whom unwittingly reveals his parental status. This exchange is a masterstroke, offering a glimpse into Alex's motivations without explicitly confirming his relationship to Kitty. Post-dinner, Alex finally discloses his connection to Professor Lee, admitting that he came to KISS upon discovering the professor is his father. This revelation is a game-changer, complicating Kitty's quest for answers and adding a new layer to her relationship with Alex.
Meanwhile, Dae's Chuseok is a heartwarming family affair, with Yuri joining them for dinner. The developing friendship between Dae and Yuri is palpable, though it's marred by Yuri's deceitful interception of a gift from Kitty—a necklace and an apology note. This act of betrayal foreshadows future conflicts and adds tension to an otherwise peaceful holiday. Principal Lim's relationship with Kitty's mother is further complicated when Yuri attempts to inquire about their history. Principal Lim's insistence that they were merely roommates is contradicted by her secretive destruction of a photo, suggesting a deeper, hidden connection.
The episode concludes with a dramatic reveal: Principal Lim burning a photo of herself and Kitty's mother, an act that speaks volumes about the untold stories of their past. This final scene is a powerful reminder that the truth often lies beneath the surface, hinting at a more complex narrative yet to unfold.
"TBH" is a standout episode, rich in cultural exploration and emotional depth. It masterfully balances the warmth of Chuseok with the suspense of unfolding family secrets. Kitty's journey is at the heart of the episode, as she navigates the complexities of friendship, family, and the search for her roots. The episode ends on a note of anticipation, leaving viewers eager to uncover the hidden truths that lie ahead.
