In a dramatic turn of events, Garo Sero unveiled what they claim is a handwritten letter from the late actress Kim Sae-ron to actor Kim Soo-hyun, written after she received a second debt notice. The letter, reportedly dated April 2024, was shared on March 25, 2025, amidst an ongoing controversy involving the two stars.
According to a close friend of Kim Sae-ron, the actress had been desperate to contact Kim Soo-hyun but was unable to reach him directly. In an attempt to deliver the letter personally, Kim and her friend visited the apartment complex where the actor lived. However, due to tight building security, they were unsuccessful in delivering the letter. The friend explained that she shared this story to emphasize how earnestly Kim Sae-ron had tried to reconnect, while Kim Soo-hyun allegedly continued to avoid her.
A part of the unreleased handwritten letter from the late Kim Sae-ron has come to light, revealing her attempt to meet Kim Soo-hyun in person rather than go through his cousin and agency co-founder, Lee Ro-be. While the full contents of the letter remain undisclosed, it is known that Kim Sae-ron expressed her desire to resolve matters privately and directly with Kim Soo-hyun, suggesting she no longer trusted intermediaries.
Garo Sero quoted an excerpt from the letter, which reads, "Oppa, please help me… We were together for six years—surely there are still loving memories between us? Please don’t be like this… I hope you’re the one reading this letter, not Lee Ro-be." This poignant plea highlights the emotional turmoil Kim Sae-ron experienced, adding layers to the narrative surrounding their relationship.
In addition to this letter, Garo Sero also revealed the existence of another handwritten note by Kim Sae-ron, reportedly written after the passing of her close friend Moonbin from ASTRO in 2023. In this note, Kim Sae-ron stated, "Kim Soo-hyun, the first man I dated and met since high school." This line has added further fuel to the ongoing controversy, as it suggests a possible relationship timeline that contradicts previous claims made by Kim Soo-hyun’s side.
As the revelations continue to unfold, the public's interest in the relationship between Kim Sae-ron and Kim Soo-hyun has intensified. According to an anonymous friend close to the late actress, Kim Sae-ron had grown increasingly weary of public attention and online gossip, which worsened her mental state. The friend also delivered a strong criticism of YouTuber Lee Jin-ho, claiming that "he played a major role in Kim Sae-ron’s downfall" and directly accusing him of being a driving force behind her emotional suffering.
Following the release of Lee Jin-ho’s videos, the anonymous friend revealed that they had independently conducted a search trend analysis using AI tools. Through this analysis, they discovered that keywords related to Kim Sae-ron, most of which carried negative connotations, had surged in popularity and become trending search terms. The friend expressed concern over how such viral, algorithm-driven content amplified public scrutiny and hate, further isolating Kim Sae-ron during an already difficult period in her life.
These newly surfaced details have only intensified calls for accountability amid the ongoing controversy. In the wake of the turmoil, Kim Soo-hyun has filed a lawsuit against Garo Sero, Kim Sae-ron’s family, and a woman identifying herself as the late actress’s aunt. The suit accuses them of distributing a private photo of the actor “washing dishes without pants,” claiming it violates the Act on Special Cases Concerning the Punishment of Sexual Crimes, particularly concerning illegal filming and dissemination.
However, media outlet CBS questioned the legal strategy behind the lawsuit, specifically why Kim Soo-hyun had not also filed a defamation case, a common route taken by celebrities facing serious public accusations. As CBS points out, it’s not the photo that severely damaged Kim Soo-hyun’s reputation and brand partnerships, but rather the allegations of an inappropriate relationship with a minor.
Despite the gravity of those claims, Kim’s legal team has thus far chosen not to pursue defamation charges. This has sparked growing speculation online. Some netizens have begun to question whether Kim Soo-hyun’s silence on the defamation front could be due to elements of truth in the allegations. They argue that if the actor were entirely innocent, he would be expected to respond with urgency and determination to clear his name, especially with his nearly 20-year career hanging in the balance.
In response, his agency Gold Medalist issued a statement, explaining that while they are “currently considering a defamation suit against Kim Sae-ron’s family,” they have “held off out of respect for the family’s grief over their daughter’s passing.” As more personal documents and allegations continue to surface, public sentiment remains deeply divided.
Whether the letters are ultimately authenticated or not, the implications are profound, raising serious questions not only about the timeline of Kim Soo-hyun’s relationship with Kim Sae-ron but also about how truth and reputation are navigated in the court of public opinion. The ongoing saga surrounding these two prominent figures continues to unfold, leaving many wondering what the future holds for both Kim Soo-hyun and Kim Sae-ron's legacy.
