What Is Rules of Dating About?
The premise of Rules of Dating in 273 words, with nothing given away. The full story follows below.
In the austere halls of a contemporary high school, an introverted, emotionally detached educator steps into a new role as a student‑teacher, navigating a world where professional decorum and personal longing intertwine. The school’s routine—classroom chatter, the hum of fluorescent lights, and the ever‑present undercurrent of adolescent ambition—serves as a quiet backdrop for a figure who prefers observation over participation, measuring each interaction with the precision of a careful scholar.
Overseeing this uneasy apprenticeship is a younger, unapologetically confident supervisor whose reputation for unabashed sensuality precedes them. Lee Yu‑rim finds herself both drawn to and unsettled by this dynamic, as the supervisor, merely a year her junior, exudes a magnetic mix of authority and reckless candor. Their professional relationship is further complicated by an unexpected confession made during a school trip, a moment that blurs the lines between mentorship, desire, and the unspoken rules that govern both.
Both Lee Yu‑rim and her supervisor, Choi Hong, grapple with an internal tug‑of‑war between duty and yearning. The narrative probes the tangled power structures inherent in a workplace where age, rank, and gender expectations clash, while also reflecting on the broader ethical questions that surface when personal motives intrude upon institutional responsibilities. The tone oscillates between detached introspection and simmering tension, inviting viewers to contemplate the fragile balance between restraint and impulse.
Against this backdrop of muted corridors and whispered rumors, the film establishes a mood that is both contemplative and charged, hinting at the complexities of modern romance within hierarchical spaces. The audience is left to wonder how far each character will go before the unspoken boundaries that hold their world together begin to crumble.

Spoilers ahead
Lee Yu-rim, a high school English teacher, becomes drawn to Choi Hong, a student teacher who is one year older than her and who already has a boyfriend. Hong is cynical and often plays hard-to-get, making Yu-rim’s early advances feel one-sided. During a night out for drinks, Yu-rim bluntly tells Hong that she wants to have sex with her, an admission that leaves Hong unimpressed.
As they continue to interact, the pair begins to question not only what they want from each other but also what they want from themselves, especially as Hong’s boyfriend shows little interest. Hong’s past becomes a backdrop to their evolving connection, and she is revealed to carry a trauma from being framed as a stalker by a married former lover, an ordeal that led to her firing from a previous school and made her wary of love, prompting a search for stability over romance.
From the moments they share, they form a growing sense of common ground and start to understand one another more deeply. Yet the narrative is complicated by rumors spreading on the school website, which frame the traumatic episode as a matter of promiscuity on Hong’s part. Hong sues Yu-rim to protect her image and to reveal Yu-rim’s alleged inappropriate behavior, and Yu-rim is fired from her job for inappropriate conduct in the workplace involving Hong.
In the end, Hong and Yu-rim reconnect as a couple, with Hong expressing gratitude to Yu-rim for helping end the insomnia that haunted her after the traumatic events.
