Spoilers for Netflix's XO, Kitty follow.

As a rom-com series, the plot of Netflix’s To All The Boys movies, the series XO, Kitty follows the experiences of Kitty Song Covey as she studies at the Korean Independent School of Seoul (KISS), the school where her mother previously went and Kitty's first boyfriend presently goes.

XO, Kitty heavily features Kitty learning about her mother, but the series also revolves around romance. The titular main character sets off on this journey in a relationship with Dae, but she finds herself involved in multiple potential romances. The self-proclaimed matchmaker also has a hand in helping others find love. Plus, the series starts out with multiple other established relationships. Ultimately, with so many romances featured in XO, Kitty, not every pairing has the same strength and potential.

14 Jina And Mr. Han

The Hans Have An Unhappy, Unhealthy Marriage

All things considered, these two are the worst romantic couple in XO, Kitty.

Mr. Han is constantly mean to his family, not seeming to care about the way he treats his wife, Jina. He decides to leave his wife alone on Chusoek, an important Korean holiday meant to be spent with family. When Jina shares that she has a son, he yells at her to pay her son off and make him go away instead of even wondering how Jina feels about finding out her son is in town.

Later, he even calls her son a problem. She finally has the strength to confront him about how unhappy she is, and he calls her spoiled. By the second season of the show, Yuri and her father are not really speaking, but she does mention that her parents are divorcing. That seems to be the best thing for them. All things considered, these two are the worst romantic couple in XO, Kitty.

13 Min Ho And Stella

Their Relationship Is Built On Lies

At first, Min Ho and Stella seem like a fun match. Min Ho is not all that interested after Kitty sets them up, but he finds himself intrigued when she is the first person he meets who stands up to his father. She also appears to be thoughtful, packing sandwiches when he accompanies Kitty to meet her relatives. All of that, however, is calculated by Stella, who is really a teenager named Esther out to get revenge against Min Ho’s father.

Stella is more nefarious than any other character on the show has ever attempted to be. While it is understandable that she is angry that the world treated her as a punchline when she attempted to compete in a reality show, her way of getting justice is over the top and could hurt more people than it helps. She also has an entire relationship with Min Ho built on lies.

12 Jina And Daniel

The Relationship Between These Former Lovers Is Underdeveloped

Jina and Daniel, aka Mr. Lee, get almost no time together, and their former romance isn’t even revealed until halfway through XO, Kitty. The only thing she tells Kitty about their relationship is that he was her first love and has good taste in music. The two don’t even get a meaningful scene together in the series. The last the audience sees of them together is Jina taking her son, Daniel, and Yuri to talk together.

It is clear that the group talks off screen and that they likely have an amiable relationship. Yuri and Alex bond, chatting, giving one another advice, and shopping together in season two. Alex even lives with his father during the break between semesters, getting to know him better. Daniel and Jina, however, do not get more time together. The audience does not get to see what drew them to one another other than their mutual love for early '90s hits.

11 Juliana And Praveena

This Couple Deserves To Be Explored More

Juliana and Praveena do not get to interact much in the second season of XO, Kitty. Most of Juliana’s screentime is embroiled in drama with Yuri, but she does it that she finds Praveena very cool when she finds out Kitty is going on a date with her early in the season. By the end of the season, Juliana and Praveena, however, have “connected” at a recent dance.

It’s early in their relationship, and they could very well end up as just friends in a possible season three of the show. The trouble is the audience does not know how they connected, though it presumably had to deal with their mutual issues caused by Yuri and Kitty’s kiss, and does not get to see them interact beyond Juliana’s explanation to Yuri.

They could have a very interesting dynamic if they get to be explored more as characters and as a relationship in season three.

10 Kitty And Praveena

Kitty And Praveena Are Better As Friends

If Kitty and Praveena had simply been friends from the start, they would have been much better off.

Kitty decides to explore her bisexuality in season 2. She knows she cannot explore her feelings for Yuri with Yuri dating Juliana, but she is intrigued by Praveena as soon as she meets her. Praveena is equally intrigued by Kitty, and though she suspects that Kitty is not over Yuri, she still goes on a handful of dates with her.

Kitty and Praveena clearly have fun together as Praveena has a sense of adventure that meshes well with Kitty’s need to meddle. The trouble is that Kitty is not entirely truthful about how “done” she is with her feelings for Yuri. Praveena is not looking for complications. The two are good for one another, but they are not in the same place. When Praveena learns how much Kitty truly cares for Yuri, and that Yuri kissed her, she is incredibly hurt and avoids Kitty and her friends completely.

If Kitty and Praveena had simply been friends from the start, they would have been much better off.

9 Juliana And Yuri

These Star-Crossed Lovers Get Very Little Time In XO, Kitty

During XO, Kitty, it’s established that Yuri and her best friend Juliana are in love and hiding their relationship because of their parents. They get split up after the housekeeper catches them together. That, however, is all established without Juliana being in the show for more than a handful of scenes. There was potential for these two to have a cute romance.

XO, Kitty has an 81% rating on Rotten Tomatoes.

Unfortunately, they only get three scenes together in the first season, and one is over the phone. There’s nothing wrong with them as a couple, but the show doesn’t offer enough to like them as a couple, either. That is changed in the second season as Juliana gets the chance to return to school following Yuri coming clean about everything to her mom in the season 1 finale.

Juliana and Yuri's relationship is plagued by insecurity on the part of Juliana and dishonesty on the part of Yuri. Juliana is sure that Kitty is coming between them. Yuri denies that despite it being obvious. When Yuri and Kitty kiss, the two break up, but Yuri cannot give Juliana the space to process finding out about the kiss. Yuri clings to her relationship with Juliana as the only thing that matters in her life, even completely ghosting Kitty and never talking about the kiss after.

8 Madison And Min Ho

This Fling Is Surprisingly Healthy For Teenagers

During the middle of XO, Kitty season 1, Madison and Min Ho have a fling. Rather than having different expectations, they both agree they won’t be serious from the start. They have good chemistry and spend a lot of time making out. They are fun together, and in on some of the schemes to help Kitty and Yuri. When Min Ho decides he wants something more, they have a mature breakup. Madison is ready to it she enjoys the chase but is not ready for a relationship.

They prove that not every relationship needs to be serious to be valuable. The only reason they place lower among the couples is that they never seemed to have much in common. Their connection was very face value, rather than having shared interests.

7 Kitty And Dae

Kitty And Dae Are Each Other's First Loves

In XO, Kitty, the titular character goes to KISS to surprise Dae but learns that he’s in a relationship – albeit a fake one. Throughout the rest of the series, they go back and forth between having romantic moments and fighting. They have many sweet moments, including him kissing her after detention and setting up a date on their camping trip. Unfortunately, they cannot communicate, always assuming the wrong thing about one another.

Kitty and Dae first meet when the Song Coveys are visiting Seoul at the start of To All The Boys: Always and Forever.

This makes it frustrating to emotionally invest in their relationship. So many of their issues could be solved if they just talked to each other. Ultimately, it’s good that they broke up during the ending of XO, Kitty season 1. They’ll undoubtedly still have a connection and appreciation for one another because they were each other’s first loves. Still, they need time apart to grow and learn more about themselves. If they’re truly meant to be together in the future, they’ll find their way back to each other.

Season 2 is a great example of that as they are clearly still there for one another as Dae explores a new relationship and Kitty spends some time alone, though she does have feelings for other people.

6 Q And Florian

Q and Florian Are The Most Consistent Relationship in XO, Kitty

Early in XO, Kitty, the perky teenager uses her matchmaking skills to get Q together with his crush Florian. The two develop a strong relationship with relatively little drama between them for most of the first season. They one another constantly. While their communication could be better, they offer each other patience and understanding when things aren’t perfect. They’re the perfect example of a relationship that doesn’t need chaos to be romantic.

Unfortunately, their relationship is thrown into question at the end of XO, Kitty when Florian reveals to Q that he’s cheating on tests so he can stay at KISS. This moment shows a fundamental difference in core values that is concerning for the couple. Florian does not believe he is hurting anyone by purchasing old tests, but as Q points out, he costs Dae his spot in the academic rankings and costs Dae part of his scholarship as a result. Q cannot get past Florian's desire to do the wrong thing in order to stay at school with him.

5 Dae And Eunice

Their Shared Interests Help Them

Dae and Eunice, who he jokingly called Yuri’s “follower” in the first season of the show, are paired up to work on a duet together as part of their advanced voice class. Initially, Eunice is too focused and exacting in her choreography for Dae, but they both share a love of singing that helps to bring them together. They also learn a lot about one another in the process.

Dae discovers that he underestimated Eunice in the past. She is not a spoiled rich girl who doesn’t care about her studies. Eunice is actually from the same neighborhood as Dae, shares his ambition to do well for herself, and is a good student. They find they have so much in common and are drawn to one another.

Yes, the talent competition might pit them against one another at the end of the season, but they are very good for one another before the competition exposes those tiny cracks in their relationship.
