Sweet & Sour

The soul-crushing reality of a three-hour daily commute is perhaps the most effective mood-killer ever devised by man. In Sweet & Sour, this isn't just a logistical hurdle; it’s the primary antagonist. While most romantic dramas treat distance as a poetic tragedy—think pining by windows or long, tearful letters—director Lee Kae-byeok treats it like a slow-leak in a tire. You don’t notice the car is sagging until you’re scraping the rim on the asphalt.

I watched this on a rainy Tuesday while my neighbor was aggressively power-washing his driveway, and the relentless thrum of his machine perfectly matched the low-level anxiety that permeates this film’s second act. Released directly to Netflix in 2021 when the world was still reeling from "stay-at-home" fatigue, Sweet & Sour arrived as a prickly, somewhat cynical reminder that "staying together" is often a matter of physical stamina as much as emotional will. It captures the specific, modern exhaustion of the "dispatched worker"—those corporate nomads in South Korea sent to satellite offices to prove their worth, only to find their personal lives evaporating in the rearview mirror.

The Slow Rot of the "Sweet"

The film begins with a deceptive, sugary glow. We see a bumbling, overweight engineering student named Lee Jang-hyuk (Lee Woo-je) fall for a kind nurse, Da-eun (Chae Soo-bin), while hospitalized with hepatitis. It’s classic "meet-cute" territory: shared meals, gentle encouragement, and a promise to lose weight to become the man she deserves. Then, the film skips forward. The "new" Jang-hyuk is now played by the sharp-jawed, effortlessly handsome Jang Ki-yong. He’s fit, he’s employed at a major firm, and he’s ready to build a life with Da-eun.

But here is where the "sour" kicks in. Jang Ki-yong gives a wonderfully frustrating performance here. He isn't a villain; he’s just tired. As he balances a grueling temporary assignment in Seoul with his life in Incheon, his character’s evolution from "doting boyfriend" to "guy who falls asleep during a conversation" is painfully relatable. We see the micro-aggressions of a dying flame: the irritation over unwashed laundry, the way a phone call feels like an obligation rather than a highlight. Chae Soo-bin is equally excellent, portraying a woman who is trying to hold onto the ghost of a relationship while dealing with her own grueling shifts as a nurse. Their chemistry is a masterclass in how intimacy gradually turns into polite tolerance.

Corporate Grind and the "Other" Woman

Enter Bo-yeong, played with a frantic, competitive energy by Krystal Jung (of the K-pop group f(x) and Prison Playbook). She is Jang-hyuk’s rival-turned-partner at the Seoul office. In a standard rom-com, she’d be the "temptress" or the "villainess." Here, she’s just another victim of the grind. She and Jang-hyuk are bonded not by grand passion, but by the shared trauma of being "temporary" employees working late into the night for a boss who barely remembers their names.

The film excels at showing how the workplace becomes a surrogate home. When you spend 14 hours a day with someone over instant coffee and spreadsheets, the lines blur. Krystal Jung’s Bo-yeong is messy, brilliant, and equally exhausted. The way she and Jang Ki-yong interact feels authentic to the streaming era—it’s a relationship built on convenience and proximity rather than the "star-crossed" tropes of the early 2000s. It reflects a contemporary Korean cinema trend that prioritizes the "Hell Joseon" (the struggle of the youth) over the Cinderella stories of the past.

The Trick Up the Director's Sleeve

If you think you know where this is going—a simple "guy cheats, guy learns lesson" arc—you’re in for a shock. Sweet & Sour is actually an adaptation of the Japanese novel and film Initiation Love, and it carries over a narrative structure that is designed to leave you feeling a little bit gaslit. I won’t spoil the finale, but I will say that it demands you re-evaluate everything you saw in the first twenty minutes.

Interestingly, the film was originally slated for a theatrical release in 2020 but was pushed to Netflix due to the pandemic. This move actually worked in its favor; there’s something about the "close-up" nature of streaming that suits the claustrophobia of the characters' lives. Turns out, most rom-coms lie to you; this one just gaslights you for your own good. It forces you to look at the timeline, the names, and the "sweet" beginning with a much more cynical eye. It’s a bold move that elevates the film from a standard weekend watch to a genuine conversation starter about how we perceive our own romantic histories.

While the mid-section can feel as repetitive as a daily commute—intentionally so—the payoff is worth the grind. It captures the specific fatigue of 2020s career-climbing and the way love often loses out to the sheer physics of being in two places at once. If you’re looking for a sugary escape, this isn't it. But if you want a movie that understands why your last relationship felt like it expired in the fridge, Sweet & Sour is a sharp, clever, and ultimately sobering bite of reality. Just be prepared to re-watch the first ten minutes as soon as the credits roll.
