Who Is Ki-hyeon in Endless Yearning 2L?

Seo Ki-hyeon is one of the most important characters in Endless Yearning 2L, a relationship-driven manhwa built around admiration, unbalanced affection, and emotional manipulation. From Chae Do-young’s perspective, Ki-hyeon begins as someone almost unreachable: a person she has admired on television since childhood. Their later reunion changes that image.

At school, Ki-hyeon does not simply behave like the kind, polished person Do-young remembers. His gentle smile hides a sharper and more calculating personality. This contrast creates the central tension around his character. He can appear considerate while still making choices that hurt other people, particularly when those choices help him move closer to Kim Ga-on.

The character is best understood through his actions rather than his surface personality. His appeal comes from the gap between how he presents himself and how he treats people when his priorities are challenged. That gap also explains why Do-young continues to struggle with her feelings even after recognizing the damage caused by his behavior.

Character Reading Tip

Pay close attention to moments where Ki-hyeon’s polite or gentle behavior conflicts with the result of his decisions. The contrast is central to his characterization.

The Gentle Image

Ki-hyeon is introduced through admiration and an appealing public presence. His smile and controlled behavior make him easy to idealize.

The Calculating Side

His choices reveal that he is willing to plan around other people’s emotions when pursuing his own goals.

The Emotional Blind Spot

His focus on Ga-on causes him to underestimate the pain and attachment experienced by Do-young.

Ki-hyeon’s Relationships and Emotional Priorities

Ki-hyeon’s relationships form the structure of the story. His connection with Do-young is based on unequal knowledge and unequal emotional investment. Do-young carries years of admiration into their reunion, while Ki-hyeon views her more instrumentally because of his feelings for Ga-on.

That imbalance does not mean Do-young’s emotions are insignificant. Instead, it makes the relationship more painful. She understands that she is being used, yet her feelings do not disappear simply because the situation is unfair. The resulting tension comes from the distance between what she knows and what she continues to hope for.

RelationshipEmotional balanceMain tension
Ki-hyeon and Do-youngUnequalHer sincere attachment conflicts with his strategic behavior
Ki-hyeon and Ga-onDeeply desired by Ki-hyeonHis pursuit of Ga-on shapes his treatment of others
Do-young and her feelingsPersistent but painfulAwareness does not immediately overcome affection

The relationship with Ga-on is especially important because it explains Ki-hyeon’s decisions without excusing them. He is not using Do-young randomly; he is using her as part of an attempt to gain the love of someone who matters deeply to him. This motivation gives his actions narrative logic, but it also emphasizes his lack of consideration for Do-young.

Why Do-young Cannot Easily Let Go

Do-young’s attachment began before she knew Ki-hyeon personally. She admired him from a distance, which allowed her to build an idealized image of him. When they meet again in high school, that image is challenged, but it is not instantly replaced.

Long-term admiration can be difficult to separate from personal love. Do-young is not only reacting to Ki-hyeon’s present behavior; she is also holding onto the person she believed he was. This distinction helps explain why repeated hurt does not immediately end her feelings.

Emotional factorEffect on Do-young
Childhood admirationCreates a strong idealized attachment
Reunion at schoolBrings the imagined person into direct contact
Ki-hyeon’s attentionReinforces hope even when his intentions are unclear
Repeated emotional harmCreates conflict between self-protection and desire
Relationship Warning

Ki-hyeon’s affection for Ga-on does not make his treatment of Do-young healthy. Understanding his motivation is different from approving of his manipulation.

Step-by-Step Guide to Understanding Ki-hyeon

The clearest way to analyze Ki-hyeon is to follow the progression of his role in the story. His characterization depends on gradual contrast: admiration comes first, the reunion adds uncertainty, and his relationship strategy reveals the deeper conflict.

1

Start With Do-young’s Admiration

Establish how Do-young sees Ki-hyeon before their reunion. Her childhood admiration explains why she gives his presence unusual emotional importance and why his approval affects her so strongly.

2

Compare Image and Behavior

Separate Ki-hyeon’s gentle public image from his calculating private decisions. This comparison prevents a surface reading that treats his smile or courtesy as proof of sincere romantic intent.

3

Identify His Real Romantic Goal

Track the importance of Kim Ga-on. Ki-hyeon’s feelings for his childhood friend are the motivation behind his decision to involve Do-young in his plans.

4

Measure the Cost of His Choices

Consider how Do-young is affected each time Ki-hyeon treats her as a means to an end. Her continued feelings make the consequences emotional rather than merely strategic.

5

Separate Explanation From Redemption

Ask whether Ki-hyeon changes his behavior, accepts responsibility, or continues relying on manipulation. His motives explain the conflict, but his actions determine whether he earns trust.

Analysis questionWhat to examine
What does Ki-hyeon want?The love and attention of Kim Ga-on
Who pays the emotional cost?Chae Do-young is repeatedly placed in a painful position
What creates reader tension?The difference between Ki-hyeon’s appearance and conduct
What would meaningful growth require?Honesty, accountability, and respect for Do-young’s agency
Best Analysis Method

Follow the consequences of Ki-hyeon’s decisions instead of judging him only by his intentions. The story’s emotional weight depends on that distinction.

Ki-hyeon, Do-young, and Ga-on: Story Function

The three central characters create a triangle shaped less by equal competition than by unequal information. Ki-hyeon knows what he wants, Ga-on occupies the position of his true romantic interest, and Do-young is drawn into the conflict while carrying the strongest visible emotional burden.

This structure makes Do-young especially important to the reading experience. Although Ki-hyeon’s plans drive the conflict, the story’s emotional perspective is closely connected to the person being used. Her reactions expose the difference between romantic longing and a relationship built on mutual respect.

Ki-hyeon’s Function

He creates movement through deliberate choices and forces the romance to confront manipulation, secrecy, and divided loyalty.

Do-young’s Function

She gives the conflict emotional depth by continuing to feel attached even after recognizing the unfairness of the situation.

Ga-on’s Function

He represents the affection Ki-hyeon wants most and becomes the reason Do-young is treated as part of a larger plan.

Story elementKi-hyeon’s contributionReader impact

Character contrastMaintains a soft exterior despite sharper choicesEncourages close reading
Emotional stakesTreats Do-young as a pawnMakes the conflict personal
Future possibilityMust confront the consequences of his actionsRaises questions about accountability

A useful interpretation is that Ki-hyeon represents the danger of confusing desire with entitlement. He wants a specific person, but his pursuit becomes harmful when he assumes other people can be arranged around that goal. The more clearly Do-young understands this pattern, the more important her own boundaries become.

Key Theme

The central question is not only whether Ki-hyeon loves Ga-on. It is whether love can justify using another person as a tool.

Reader Checklist: Tracking Ki-hyeon’s Development

Use this checklist when reviewing new chapters or comparing Ki-hyeon’s early and later behavior. It focuses on observable character development rather than predicting an outcome that has not been established.

Character Development Checklist:

  • Compare Ki-hyeon's public image with his private decisions
  • Track every situation where Do-young is used to influence Ga-on
  • Note whether Ki-hyeon recognizes Do-young's feelings
  • Look for direct honesty instead of indirect manipulation
  • Check whether his actions produce accountability or repeated harm
Development signalPositive movementConcerning pattern
CommunicationStates his intentions clearlyHides motives behind a gentle image
Treatment of Do-youngRespects her choices and boundariesUses her cooperation for another relationship
Feelings for Ga-onPursues mutual understandingTreats others as obstacles or tools
AccountabilityAcknowledges emotional damageFocuses only on achieving his goal

What Would Count as Real Growth?

A convincing change would require more than regret or a dramatic confession. Ki-hyeon would need to understand that Do-young is a person with independent feelings, not merely a useful participant in his pursuit of Ga-on. He would also need to accept that good intentions do not erase repeated harm.

The most meaningful signs would include direct communication, respect for refusal, and a willingness to face consequences without redirecting blame. Until those elements appear, readers should treat any softer behavior cautiously.

Review Tip

When assessing Ki-hyeon’s development, prioritize consistent behavior over isolated moments of kindness or emotional vulnerability.
