In the seventh installment of Dear Hyeri, we delve deeper into the complex life of Eun-ho, who grapples with her dual identity as Hye-ri. The episode opens with Eun-ho's decision to live as Hye-ri, a move aimed at understanding the source of Hye-ri's happiness. This decision leads her to work at a parking station, where she encounters Joo-yeon under the guise of Hye-ri. Their interaction is laden with subtleties; Eun-ho, as Hye-ri, mentions having an older sister, while Joo-yeon's excuse for visiting Hye-ri's house is driven by his longing for her company.

The narrative takes an interesting turn when Eun-ho, still posing as Hye-ri, participates in a team dodgeball match with Joo-yeon. Her exceptional performance not only earns her accolades but also strengthens the bond between her and Joo-yeon. The day's events culminate with Joo-yeon returning Eun-ho's lost phone, repaired and ready for use. Eun-ho's claim that the phone belongs to her sister raises Joo-yeon's suspicions, despite his apparent understanding.
The following day, Eun-ho's attempt to reinstate Hyun-oh on the 9 pm news slot is met with resistance. Her efforts to persuade the team manager are fruitless, but she remains undeterred. Meanwhile, Hyun-oh faces his own challenges, being asked to move back to a cubicle and later being assigned to a joint project with Eun-ho.
The project brings Joo-yeon and Eun-ho together professionally for the first time. Joo-yeon's recognition of Eun-ho's hand wound from the dodgeball game sparks a series of revelations. He discovers that Eun-ho and Hye-ri are the same person, and that Eun-ho has been living with dissociative identity disorder. Joo-yeon's discovery is a pivotal moment, as he learns the truth about Eun-ho's condition and her relationship with Hyun-oh. Despite this, Joo-yeon's determination to wait for Hye-ri's return is a testament to his growing affection for her.
Back at the office, Jae-yong's successful debut on the 9 pm news broadcast is a surprising triumph. Eun-ho, upon hearing the news, is reminded of Hyun-oh's relentless efforts to secure the same slot for his mother's sake. These flashbacks humanize Hyun-oh and provide insight into his motivations.
The episode concludes with Eun-ho overhearing rumors of Hyun-oh's impending marriage, leading to a dramatic confrontation between the two. The final scene, where Eun-ho and Hyun-oh lock eyes, is charged with emotion and leaves viewers eager for the next episode.
In the epilogue, Eun-ho's diary entries to Hye-ri, titled "Dear Hyeri," offer a glimpse into her inner turmoil and the depth of her struggle with her dual identity. These entries serve as a poignant reminder of the emotional weight Eun-ho carries as she navigates her life as both Eun-ho and Hye-ri.
Episode 7 of Dear Hyeri is a masterclass in storytelling, expertly weaving together the threads of Eun-ho's complex life. It balances the emotional gravity of Eun-ho's condition with the unfolding drama of her relationships with Joo-yeon and Hyun-oh. The episode's climax, coupled with the epilogue, leaves a lasting impression, setting the stage for the drama's continuation.
