The third episode of Season 2 of "XO Kitty" kicks off with Kitty once again seeking forgiveness from Juliana. It transpires that Yuri has decided to leave the dormitory to reside with her mother. Despite Juliana's reluctance to reconcile, Kitty attempts to engage her in lighthearted conversation about Praveena. Nevertheless, Kitty can't conceal her enthusiasm about her renewed opportunity with Praveena.
Meanwhile, Dae arrives at school after being dropped off by his father, and they share a nostalgic moment by listening to his mother's favorite songs. It seems that Dae's father has been overworking himself to the point of exhaustion. Dae's concern grows, but his father reassures him that he's fine. At the same time, Yuri enters the school and approaches Dae, confessing that her home life remains tumultuous and that she yearns for the companionship of Juliana and Kitty. Ironically, Kitty's inadvertent revelation has spared Yuri and Juliana the need to conceal their relationship.
Elsewhere on campus, Mr. Moon praises Stella and Min-ho for Stella's bravery in defending his son. He invites Min-ho to join him at the family cabin for the upcoming Lunar Year celebrations. However, Min-ho suspects that his father is only using him because his other children are occupied. Stella persuades him to give his father a chance.
During the school assembly, it's announced that it's time to unveil the yearly time capsule of the graduating class 40 years ago, along with the documentaries featuring the Heritage Scholarship Foundation students of that era. Unfortunately, due to financial constraints, the school has decided not to showcase the time capsule.
This episode ignites Kitty's curiosity, propelling her to uncover the secrets her mother entrusted within her time capsule. However, her enthusiasm is dampened when Praveena informs her that accessing these capsules necessitates official permission. Undeterred, they hatch a daring plan to sneakily retrieve the precise capsule Kitty seeks.
Meanwhile, at the school assembly, Mr. Moon makes a thrilling announcement: he intends to organize a student talent show at semester's end, with a cash prize awaiting the victorious performer. The room buzzes with excitement as Q tries to persuade a hesitant Dae to participate. Later, Min-ho steps in, convincing Dae to form a pop duet with Eunice for the contest.
After the assembly disbands, Juliana confesses to Kitty about borrowing her idea to assist Yuri, relieved to find that Yuri bears no ill will. Elsewhere, Jin finds himself entangled in a misunderstanding, mistaking his playful antics with Jin for flirtatious gestures.
As night falls, Praveena, Min-ho, and Kitty embark on a clandestine mission, breaking into the archives to pilfer the coveted time capsule. Kitty confides in Praveena her desire for a proper date, while Min-ho extends an invitation to Praveena and her friends to join him at his cabin for the Lunar New Year celebrations, hoping they can serve as a buffer between him and his father's stern presence.
The following day, Kitty invites Yuri to watch Eve's documentary, sparking an urban treasure hunt for VHS players. Unfortunately, Yuri's tardiness causes her to miss Juliana's art exhibition, igniting Juliana's ire, especially upon discovering Yuri's company was with Kitty. Simultaneously, Praveena ponders if Kitty has truly moved on from Yuri, to which Kitty responds with a deceitful affirmation, fueling Praveena's hopes. They agree to use the cabin weekend as a test of their budding romantic connection.
Elsewhere in the narrative, Min-ho and Stella's bond remains unshaken. Eunice initiates a flirtatious onslaught on Dae, leaving him utterly flustered. Q, finally comprehending Jin's weighty burden of maintaining the family marathon legacy, opens up about Jin's hurtful actions, paving the way for reconciliation between them.
Prior to embarking on their journey, Kitty and Yuri immersed themselves in Eve's poignant video, reliving a heart-wrenching moment as they witnessed the youthful exuberance of their mothers. Kitty's heart swelled with joy upon hearing Simon's voice faintly in the background, yet a tinge of sadness enveloped her as she watched her mother speak fondly of the future she had envisioned. She was also startled to discover that her mother had been aware of the existence of her other aunt, a revelation that shone a light on the primary reason behind her mother's journey to Korea—a quest to reunite her fractured family.
Caught in a whirlpool of emotions, Kitty and Yuri's bond deepened, culminating in a tender kiss from Yuri that sealed their shared vulnerability. However, their intimate moment was abruptly interrupted when Min-ho, to their utter astonishment, caught them in the act, leaving the episode on a cliffhanger.
