People say the ending is shallow or too sudden, and technically it may be, but from context clues I can guarantee you this is a terrible end for Joy
Hi, I'm Lenightmare, a lesbian trans woman. I'm unemployed. Also my ADHD tests (which y'all should do) says I'm supposedly very good at interpreting things. I don't think this is enough to legitimize what I'm about to write, but whatever, I think y'all need a better explanation of what happened
In the story, we're introduced to our three characters, Joy, Namsu and Hye-Yeon. Even though Joy is the titular character, it becomes clear we're not exactly following her perspective, the entire manga takes place in Namsu's and Hye-Yeon's view of what happened, and thus it's hard for people to understand exactly what's going on with Joy, but hopefully through reading this you can understand her better, and see just how much miserable she's become by the end.
One very important character that barely appears is Hye-Gyung, if this were a literature classic, she probably wouldn't even exist, but the author, consciously or not, decided not having a character like this would make things even more confusing. Hye-Gyung isn't a character exactly, she's more of a part of Joy, a fragment of her consciousness, that comes up to remind her just how important this moment is. In the first chapter, Hye-Gyung asks if Joy is thinking of her boyfriend, an early sign that Joy may think of Hye-Yeon as a potential partner. After that, we're introduced to Namsu, and a similar situation happens with Namsu's coach, finally giving us the main gist of the manga.
We start by seeing Namsu's view of things, how she's clearly in love but unsure of what these feelings actually are. She sees Hye-Yeon take advances on Joy, both casually and more intimately and feels uneasy, finally understanding that she isn't okay with Joy maintaining their relationship as just friends. Hye-Yeon helps her understand that a lesbian relationship is okay, and she, through her struggles with running, discovers the toll of the uncertainty that is Joy dating someone else.
Once more, Hye-Gyung comes in to help make things clearer. She motivates Namsu to be true to her feelings, to not be afraid to tell Joy just how much she loves her and the intentions she has. By this point, Joy is still clueless as to what's happening, Namsu's running time is being directly affected by her feelings, and if she doesn't act quick, Namsu won't be able to participate in the nationals. Joy, after cheering Namsu, goes to the classroom with Hye-Yeon, and this is the first scene I think a lot of people neglected to analyse. This is one of the most important scenes in the whole manga, not for Namsu, but for Joy.
In that classroom, Joy, whose feelings were still being developed, discovers lust, pleasure, and the excitement of a sexually active relationship. It's in this moment she starts to desire Hye-Yeon, not when they first met, not when they got separated, not when they kissed (although that did show her a glimpse of what was to come), but now, during their more intimate moment in the classroom.
Chapter 9 is when Joy finally understands just what she's gotten into. Her classmate explains to her Namsu's underperforming runs, and that she couldn't be ignored anymore. Hye-Gyung the goat comes once again to clarify things, and tells Joy she has a choice to make. Here, Hye-Gyung not only represents Joy's consciousness and the sudden realization that she needs to choose one, but also the pressure from the students. It's clear Namsu likes Joy, and the students want Joy to date Namsu just to improve her times, thus giving her a legitimate chance to win the nationals.
Hye-Gyung, once again acting as Joy's consciousness, asks Joy if she made a choice, which Joy responds vaguely. Joy herself is unsure of her choice, but still acts cheerfully and moves on, blinded by her desire to keep things as they are. She has a talk with Namsu over their feelings for one another and Joy decides to date Namsu. I want this to be very clear, at this moment, Joy hasn't actually figured out her feelings for Namsu, even though later, when we're shown her thought process behind her decision, she says she likes them both. She's moved by Namsu's feelings, and wants to reciprocate it, but she's not really sure of her feelings just yet, she is dating Namsu merely because of the pressure the school is putting on her, and the worries she has as shown by her saying in chapter 23 she doesn't want her to feel lonely. This backfires immensely, but we'll get there when we get there
Chapter 12 shows us the dreaded scene, but with a few parts censored as to not spoil those who didn't figure out joy just yet. The following chapters are focused on Namsu working on her jealousy and envy. Joy says she doesn't want Namsu to publicly announce their relationship because she's worried of the social pressure she'll suffer, but truth be told, the two of them getting together is exactly what people want. It improves Namsu's times, giving her the chance to go to the nationals.
Chapter 14 and 15, just like the classroom scene, are two of the most important chapters in the whole manga. Joy and Namsu go on their first and only date. It's here that Joy discovers the intimacy of pure love, the happiness that walking and talking with the person she loves conveys, which is very different from the instant pleasure of lust. In the night that follows, Joy, influenced by Hye-Yeon's forwardness, asks Namsu to have sex, and Namsu refuses, as they just got dating, which is fair, but not enough for Joy. The mere concept of a relationship to Joy is entangled by lust, by the immediate pleasure and carnal feeling that sex offers, and, after receiving a call from Hye-Yeon, decides to go check on her to see what's wrong, and they end up having sex.
We see Hye-Yeon's backstory, how she came to conclude she loves Joy, and how she became so sexually active. This is made to legitimize her feelings to the readers, showing that what Joy is doing is not only hurting Namsu, but Hye-Yeon herself. Chapter 21 may seem laid back, but it shows us a bit of what Joy is thinking. Joy is dating the two of them as if she's dating a single person. On one side, we have Hye-Yeon, who showed her the pleasures of lust, the feeling of being physically wanted, and on the other side we have Namsu, who showed her lust isn't everything there is to it, the pure feeling of loving each other without necessarily wanting sex is new but exciting to Joy, and by choosing the two of them, she feels as if she can have both sides of the coin, seeing as each one provides something that the other side can't.
as I mentioned previously, chapter 23 shows a bit of what's going on in Joy's mind during the time she had to make a choice. As we've come to understand, she concludes that dating both of them is the only solution, seeing as choosing one will leave the other lonely. We're also shown that Hye-Yeon is purposefully showing herself with Joy more as to convey the feeling they're intimate to their classmates. Hye-Yeon understands the choice Joy did, but feels it's not enough, she can't be satisfied having part of Joy, so she tries what she cans to get her fully. Rumors spread, and Namsu is told Joy and Hye-yeon were seen kissing in school.
Back in chapter 22, Namsu confronts Joy about these rumors, stating she wants joy to be faithful, which Joy responds aggresively, claiming she should be more sexually active with her, and the chapter ends with Namsu promising Joy to have sex with her after she gets the medal, to which Joy feels proud. This is a very big promise, Namsu essentially said she'll become the country's greatest high-school runner and get a medal just for Joy. In her mind, Joy is still tainted by her desires, lust still plagues her definition of a relationship, but hearing such big promise moves her, the feelings conveyed by Namsu's words are strong, and it's going to affect her, you'll see how.
Back to the present, Joy, having taken a picture with Hye-Yeon after they had sex, accidentally sends it to Namsu, resulting in disaster. The three of them have a confrontation, and this scene is full of context clues of what is going on in Joy's mind. Here, Namsu and Hye-Yeon aren't just representing themselves, but also Joy's mind. Namsu, which is the part of Joy that understood the feeling of being loved and not just physically wanted, is disgusted by what Joy is doing, and feels the other party is corrupting her, hurting them all in the process. Meanwhile, Hye-Yeon, which is the part of Joy that sides with the immediate pleasure of sex, gives empty excuses, stating Namsu isn't present enough for Joy, which is a very flawed argument considering she knew that Namsu was going through a lot, and still decided to date her. That's all this part of Joy can do, lie to herself, give flawed explanations to what she's doing, being dishonest. Joy foolishly follows Hye-Yeon's offensive, and as we're about to see, this forever affects her.
After this experience, Namsu falls off the stairs and sprains her ankle, disqualifying her from the nationals. I think this is where people feel the author went overboard, and I understand that. It's as if Namsu is being punished for merely doing what Joy allowed her to do, innocently. She didn't do anything wrong, so why is she being punished? Once again, Namsu, in taking that fall, is also representing her side of Joy's consciousness. Joy is finally aware of what she just did. By ending her girlfriend's dream, she hurt everyone in the process. Hye-Yeon and Namsu fought, Hye-Yeon felt conflicted from the beginning, and Namsu's first year in high-school is forever changed, and now, Joy finally notices what she subconsciously noticed a long time ago, that Hye-Yeon couldn't give her what Namsu gave, the feeling of pure love, the feeling of being wanted not just for carnal acts, but for respect and well-being.
This, I think, is where most people fail to understand exactly what the author is conveying. The last few scenes are of Hye-Yeon's uncertainty and insecurity of Joy's reciprocate love. This isn't to punish Hye-Yeon, not directly at least, this is to show Joy is now incomplete. She will forever think of her mistakes, the pure love she abandoned in favor of a shallow, fading carnal feeling. The last scene is of Joy seeing Namsu's pictures, crying, and asking if Hye-Yeon will always be by her side. By asking this, Joy is reminding herself of the future she chose, how she chose sex over love, how she will probably never have this feeling with Hye-Yeon, or heck, ever again. It's in this final moment that Joy realises, Namsu loved her, really loved her, and she loved her too. What started as pity and societal pressure ended up being legitimate feelings, feelings that will never fade, and will never settle.
In the end, bellow Namsu, bellow Hye-Yeon, we find Joy. A girl who picked the immediate pleasure, the present, over the future, the forever lasting love. Sure, Namsu lost her chance at the nationals this year, but as her own coach said, she still has next year. Sure, Namsu lost her friend, her lover, and will transfer schools, but she will grow, we all do, the emotions she conveyed will forever last, if not to joy, to other women she eventually will fall in love to. Hye-Yeon seems doubtful of Joy's feelings, but exactly like lust, she doesn't care. She has Joy, and that's what matters. She will forever be on Joy's side, because having Joy for herself is more important than Joy's well-being. And Joy, the girl who had multiple opportunities to choose, decided to throw away her true love, the one that truly cared about her, over someone she feels is superficial, someone who only really cares about themself, and thus, I'd say Joy had the worst ending by far. I'm not saying she's innocent, but I disagree when it comes to people saying the author was too rough on Namsu, or that Joy went unpunished. The manga clears something to us very soon into it, Namsu has a future, moreso than the other two. She has the capacity to compete with the nation's best, and she's still on her first year of high-school.
Joy and Hye-Yeon are destined to end, Hye-Yeon's feelings are but a passing wave of pleasure that plagues Joy's memories. Joy will be scarred by this, and will possibly never find what she found on her date with Namsu, and Hye-Yeon, without Joy, has nothing as stated in her backstory, she's dependant on a fragile and insecure relationship that will result in Joy's traumas only growing stronger
