Dear Hyeri

Eun-ho disappears and no one can get in touch with her for a month. Joo-yeon has been looking for Eun-ho so he even looks up Hyun-oh on the Internet and goes all the way to PPS to ask him about Eun-ho's whereabouts. He tells Hyun-oh he is dating Hye-ri, Eun-ho's other personality. Hyun-oh is utterly shocked to find out that Eun-ho is suffering from dissociative identity disorder.

Although he can't tell whether it's Eun-ho or Hye-ri, Hyun-oh takes her back home. He starts to take care of her and tries to talk to her, but she won't say anything back to him. After learning that she's now with Hyun-oh, Joo-yeon comes to meet Hye-ri. She's deeply moved by what Joo-yeon says to her. Meanwhile, Ji-on hands a piece of drawing over to Hyun-oh, which makes him realise his feelings for Eun-ho.

Eun-ho has returned to being herself and realises just how much she's missed everything about Hyun-oh. She shows up at the office, eager and ready to take on any task thrown her way. While her presence stresses Shin-joong out, he also feels a sense of relief having her back. One by one, opportunities start coming her way at work, but as always, good things come with a price.

Fear sets in after Hyun-oh escapes death, and the worry over Jae-yong's well-being renders him irremediable. Eun-ho stays by his side to console him but gives him the space he needs to recuperate. However, PPS is at its most vulnerable, unable to fill Jae-yong's spot for the 9 o'clock news. Meanwhile, Baek Hye-yeon jumps ship and joins PPS, leaving Media N Seoul out to dry, especially Joo-yeon, who begins to have a change of heart.
