The TVING original series “Dear X” concluded its run on November 27, 2025, with episodes nine and ten revealing escalating tensions and a complex web of motivations surrounding Baek Ah-jin, played by Kim You-jung. The episodes focused on the fallout from Moon Do-hyuk’s confession and subsequent actions, as the drama nears its climax.
Moon Do-hyuk, portrayed by Hong Jong-hyun, confessed his feelings to Ah-jin and proposed a marriage of convenience, explicitly linking his offer to her professional success. This revelation, marking a dramatic shift for the actor who previously starred in romantic roles, unveiled a chillingly calculating persona, described by some as resembling a sociopath. Hong Jong-hyun’s portrayal of Moon Do-hyuk was noted for its intensity and lack of remorse, particularly in scenes where he issued orders related to potentially violent acts.
Following his confession, Moon Do-hyuk attempted to eliminate rivals Kim Jae-oh (Kim Do-hoon) and Ad Yun Jun-seo by setting off a bomb at their location. Both men survived the blast. The attempt underscores the lengths to which Moon Do-hyuk is willing to go to achieve his goals, and his obsession with Baek Ah-jin.
Parallel to these events, Jun-seo’s mother faced a medical crisis, requiring a kidney transplant. Ah-jin leveraged this situation, revealing that her previous apology to Jun-seo was solely motivated by securing a kidney donation for his mother. Jun-seo subsequently agreed to donate his kidney and cover all medical expenses, but imposed conditions on his mother, forbidding her from contacting Ah-jin or his grandfather.
Meanwhile, Mi-ri was arrested on charges of embezzlement and the use of “shackle files” to control artists. Investigators accused her of misappropriating billions of won from company funds. The arrest adds another layer of complexity to the unfolding drama, highlighting the cutthroat nature of the entertainment industry depicted in “Dear X.”
Hong Jong-hyun joined the cast as a special guest, following Kim Ji-hoon and Hwang In-yeop, adding a final layer of suspense to the series. The unfolding connection between Moon Do-hyuk and Baek Ah-jin remains a central focus as the series concluded.
