The ending of the thoughtful and enticing relationship drama has left the audience baffled. If you are looking for more insight into the movie’s closing moments, we can certainly provide some. So let’s dig into it! SPOILERS AHEAD!

Sweet and Sour Plot Synopsis

‘Sweet and Sour’ opens with a Hepatitis B patient, Jang-hyeok, being admitted into a hospital. After his family and friends distance themselves from him, Jang-hyeok is cared for by the hospital nurse Da-eun. Jang-hyeok slowly starts to recover while striking a friendship with an overworked Da-eun. Soon Jang-hyeok is discharged and realizes he likes Da-eun. Jang-hyeok gets Da-eun’s number from the hospital, and she invites him over. The two spend the night together. The next morning, Jang-hyeok fixes the flickering light bulb in Da-eun’s apartment and cooks her breakfast. Da-eun is touched by Jang-hyeok’s kindness.

Soon, romance begins to blossom between the two, and Da-eun asks Jang-hyeok to accompany her on a Christmas trip to Jeju, to which he agrees. Da-eun gifts Jang-hyeok a pair of sneakers, and he commits to losing weight. Some time passes, and a slim Jang-hyeok is assigned a contract job at a bigger corporate firm in Seoul away from his home in Incheon. The long working hours, commute, and competition with his new co-worker Bo-yeong leads to Jang-hyeok neglecting Da-eun. Da-eun reveals she is pregnant but decides to get an abortion and hides this from Jang-hyeok. After a fight, the couple completely drifts apart. The climax deals with the messy fallout of their relationship, and the audience learns whether or not the couple gets back together.

Sweet and Sour Ending: Who is the Other Jang-hyeok?

During his time in Seoul, Jang-hyeok meets and eventually becomes attracted to his competitive co-worker, Bo-yeong, and spends more time with her. After his fight with Da-eun, Jang-hyeok kisses Bo-yeong and begins to ignore Da-eun. When Da-eun texts him to know if she should cancel their tickets to Jeju, Jang-hyeok tells her she can go with someone else if she wants. However, by the climax, Jang-hyeok realizes he still loves Da-eun after hearing the mention of Jeju at his office’s annual party.

Knowing that Da-eun hasn’t canceled their tickets, Jang-hyeok thinks she is waiting for him at the airport and rushes there. Upon reaching the airport, he does find Da-eun waiting there. However, as he gets out of the cab and runs towards her, he bumps into another man who turns out to be the Jang-hyeok we met at the movie’s start. Lee Jang-hyeok, the one Da-eun nursed back to health, is the person she is waiting for at the airport.

There are certainly some clues earlier in the movie that point to the fact that the person Da-eun is dating isn’t the same as the person she met at the hospital. While both share the same name and profession, Lee Jang-hyeok is a computer engineer, while it is hinted that Jang-hyeok is a structural engineer. Most of the differences in their personalities become obvious only when Jang-hyeok begins to drift away from his girlfriend, so the writers have done a great job of masking the big reveal.

It is ultimately these differences that make us realize that despite the similarities between the two men why Da-eun chooses to be with Lee Jang-hyeok. The movie ends with Da-eun going on the trip with Lee Jang-hyeok, leaving Jang-hyeok gutted, which brings us to the next point.

The Dichotomy of Da-eun and Jang-hyeok’s Fates Explained

After realizing that Lee Jang-hyeok and Jang-hyeok are two different people, the entire timeline of events unravels before our eyes as we realize that both Jang-hyeok and Da-eun were seeking comfort in other people while going through a difficult period in their relationship. This twist forces the audience to rethink the couple’s relationship.

While it seems like Jang-hyeok’s attraction towards Bo-yeong is at the root of his relationship problems with Da-eun, she is also somewhat at fault. It adds a subtext that is perhaps a commentary on the volatility of modern relationships. Without getting too heavy-handed, the film subtly points out the need for companionship and comfort today’s emerging adults face while navigating the difficulties at their demanding jobs.

What goes understated is that the more time she spends with the caring and thoughtful Lee Jang-hyeok, the more Da-eun realizes her boyfriend’s shortcomings. While there is nothing wrong with seeking companionship, Da-eun makes some questionable choices (for example: kissing Lee Jang-hyeok) given the fact that she is in a committed relationship.

Despite both being at fault for their relationship’s breakdown, Da-eun gets a sweet ending, while Jang-hyeok gets a sour one. In the final scene (disguised as a mid-credits scene), Jang-hyeok returns to his office party. Bo-yeong reveals that she won the trip to Jeju and asks Jang-hyeok to come with her. Jang-hyeok proposes to her, but she shuts him down, telling him that she isn’t quite there just yet. The harsh moment adds insult to injury for the already heartbroken Jang-hyeok.

How and where did it all go wrong for poor Jang-hyeok? Although the movie hints that Jang-hyeok’s sour ending is a classic case of karma, we do not think he deserves to be left heartbroken, especially after Da-eun’s unfaithfulness comes to light. However, though we sympathize with Jang-hyeok, he certainly only has himself to blame. Not only does Jang-hyeok misreads the needs of his partner, but he also changes his mind about who he loves twice in the same night.

Jang-hyeok’s actions in the film have a shade of selfishness, and his caring side only comes out at his convenience. There’s a fine line between selfish and self-serving that the character treads, making his ending even sadder. There’s certainly a lesson to be learned for young folks in the contrasting fates of Da-eun and Jang-hyeok.

Why Did Da-eun Lie About Her Pregnancy?

During their big argument scene, Da-eun reveals to Jang-hyeok that she got an abortion. However, we never see her actually get an abortion. In the fuzzy rewind sequence, we see the doctor explain the various precautions that Da-eun needs to take for her baby’s well-being. This explains why she gives up smoking, her increased appetite, and her constant tiredness and need for naps.

In the end, she asks Lee Jang-hyeok to carry a heavy suitcase for her. This scene makes it pretty obvious that Da-eun didn’t actually get an abortion. Not only that, but it also suggests that Lee Jang-hyeok is aware of her pregnancy and has decided to raise the baby with Da-eun. It is likely that Da-eun lied to Jang-hyeok to see how he really feels about the baby. His reaction is another hint of his borderline selfishness and is enough to show Da-eun that she does not belong with Jang-hyeok. She instead decides to raise the baby with Lee Jang-hyeok, who is more caring and understanding of her needs.
