Rules for Dating Trash: Character Guide & Romance Breakdown

Rules for Dating Trash is a romance webtoon built around a chaotic college reunion, a painful past relationship, and an attraction that Ihyeon Seon does not want to pursue. After a messy breakup forces her to step away from college for three years, Ihyeon returns at age 25 hoping to keep her senior year quiet. Her plan immediately falls apart when campus rumors, her former boyfriend, and Chanu Nam enter the same social orbit.

The official Rules for Dating Trash WEBTOON page describes Ihyeon as someone trying to avoid another relationship while Chanu keeps pulling her into his world. That conflict gives the series its main dramatic engine: Ihyeon wants distance, while Chanu treats every encounter as another reason to move closer.

Video Highlights:

• Ihyeon’s breakup has affected her education, finances, and reputation.
• Chanu is introduced as an attractive but unreliable campus figure.
• Campus forums intensify the story through gossip and harsh judgments.
• The early romance depends on awkward meetings, jealousy, and unresolved history.

The opening setup deliberately leaves important questions unanswered. Students label Ihyeon as obsessed with her ex, but the visible consequences suggest that her breakup may have been more serious than campus gossip implies. Her discomfort whenever the ex appears also indicates that the emotional damage has not been resolved.

The main cast is introduced through contrasting reputations. Ihyeon is treated as a campus subject of gossip, while Chanu has already earned a reputation as a womanizer. Neither character enters the story with a clean social image, but their reputations affect them in different ways.

Ihyeon is judged for her past, clothing, and supposed fixation on her ex. Chanu, by contrast, appears to benefit from his confidence and popularity even when his behavior is openly careless. This imbalance creates an important question for the romance: can Chanu become emotionally responsible, or will his charm remain another form of trouble?

Chanu’s introduction is intentionally contradictory. He can appear helpful or observant in one moment, then insensitive or dismissive in the next. When Ihyeon is upset, he admits that comforting people is not something he likes, yet he still asks for her phone number. That combination makes him intriguing, but it also prevents the reader from treating him as a dependable romantic lead too early.

Ihyeon’s behavior is equally complicated. She repeatedly tries to escape awkward situations, refuses to accept Chanu’s familiarity, and eventually pulls him closer when her ex approaches. That moment may look like a romantic signal, but it also functions as a defensive decision. Ihyeon is using a new social connection to communicate something she cannot say directly to her former boyfriend.

The romance in Rules for Dating Trash depends on friction rather than immediate trust. Ihyeon does not return to college looking for love, and Chanu does not initially present himself as a safe or stable partner. Their connection develops through repeated coincidences, class interactions, public embarrassment, and moments where one character notices more than the other expects.

A major source of tension is Chanu’s ability to make Ihyeon feel seen while also making her uncomfortable. He notices her appearance, remembers her name, and watches her reactions. However, he also trails after her, places an arm around her without permission, and treats awkward conversations as opportunities to provoke a response.

The possible fake-dating direction is especially compatible with the premise. Ihyeon may use Chanu to discourage her ex, while Chanu may accept the arrangement because it gives him more access to her. That setup would create opportunities for both comedy and conflict, but it would only become satisfying if the characters eventually address the difference between performance and genuine affection.

The strongest emotional question is not simply whether Ihyeon and Chanu will become a couple. It is whether Ihyeon can regain control over her own story. At the beginning, classmates define her through rumors, her ex remains part of her daily life, and Chanu keeps forcing himself into her attention. A meaningful romance should give Ihyeon more agency rather than replacing one controlling relationship with another.

Use the following sequence to track the story’s major relationship beats without losing sight of the breakup mystery.

The early arc is easiest to understand when each encounter is treated as both a romantic beat and a character test. Chanu’s approach may create chemistry, but it also exposes his lack of emotional tact. Ihyeon’s refusals may look like standard romantic-comedy resistance, yet they also communicate genuine discomfort.

For readers analyzing the series, the best approach is to avoid ranking characters only by attractiveness or popularity. Chanu’s appeal is part of the premise, but his long-term value as a lead depends on whether he can change. Ihyeon’s emotional recovery should remain equally important.

The following checklist is useful for tracking the unresolved elements of the early story and evaluating future relationship development.

Several questions remain central to the series. The breakup is clearly important, but its details are not fully explained in the available premise. The ex’s continued attempts to approach Ihyeon add pressure, while Chanu’s interest creates a new route for conflict.

The story also raises a broader theme about reputation. Ihyeon is criticized for being associated with her ex, while Chanu’s womanizing image is treated as a familiar part of his identity. That contrast suggests the series may explore how different standards are applied to men and women in the same social environment.

The official WEBTOON listing identifies the series as a romance title created by Seo Yeon and rates it for young adult readers aged 16 and older. Readers should use the platform’s content-rating information for the most current guidance.

Rules for Dating Trash stands out through the contrast between romantic-comedy energy and the consequences of Ihyeon’s past. Its strongest hooks are the missing breakup context, Chanu’s questionable charm, and the possibility that public reputations conceal the truth.
