After seeing Yi-kyung leaving town, Kang, like a crazy person, runs through the streets shouting Ji-hyun's name, wondering where the heck she is. Uh, you know she's a ghost, right? It's okay, Kang-ah, we all lose a few smart points in moments of panic.
Kang gets on the phone to try to trace Yi-kyung's taxi, begging for help because his wife has gone off to die alone after being told she was terminally ill. Aw, I know it's a lie, but it's sweet to hear Kang referring to her as his wife all the same.
Yi-soo finds Ji-hyun still slumped on the ground and takes her to Seoul Station, Yi-kyung's destination, saying this is as much as he can do for her. He tells Ji-hyun to be sure to bring her back.
Kang boards the train ahead of Ji-hyun, who follows him onboard just before it departs. He approaches Yi-kyung and introduces himself, saying that he needs her help in order to find somebody. Yi-kyung replies that she already knows, and that she's leaving because of her: "Why should I lend my body to a ghost?"
As Kang explains that Ji-hyun needs her in order to survive, Ji-hyun enters the car and sits in the seat next to him, apologizing to Yi-kyung. She sobs that she did it because she wanted so desperately to live: "Just ten more days. If you don't help me, I can't do anything. I have to just die!"
At the sound of her voice, Yi-kyung stiffens, immediately aware, and she can see the vague shape of Ji-hyun sitting across from her. Kang senses her change and asks if Ji-hyun has arrived, and Yi-kyung can't help but be moved by Ji-hyun's pleas - that she may die anyway, but she wants to use the ten days to see her parents' face one more time, and say one last word to Kang.
Min-ho meets with his new landlady in Yi-kyung's apartment and hears that some other guy came looking for her and kicked up a huge fuss, but hadn't been able to catch her in time.
That's only partially true, since Kang now drives Yi-kyung (and Ji-hyun) back in his car, and she explains that she's started to see and hear Ji-hyun recently. She also has bits of Ji-hyun's memories left in her mind, so she knows a bit of what Ji-hyun has been through, although her understanding is patchy.
Kang asks after Ji-hyun's condition, and Yi-kyung relays Ji-hyun's answer ("Tell him I'm fine") to him.
Then the Scheduler joins them, and Ji-hyun worries what'll happen now that Kang knows everything and Yi-kyung and see and hear her. Yi-soo says that it's fine, and that this is what sometimes happens when two souls are compatible: "It's because Yi-kyung is so pure."
Back at Yi-kyung's place, the two ladies sit down for a face-to-face talk for the first time. Yi-kyung apologizes for the accident, and Ji-hyun says it's not entirely her fault. Ji-hyun can't divulge the nature of her 49 days, but assures Yi-kyung that she didn't come to her out of a vengeful spirit, but that she was sent to her for another reason.
Yi-kyung tells her that in the spirit of paying back her debt (for the accident), she'll agree to continue as host for the ten remaining days.
Kang waits outside, tensing when Ji-hyun comes bounding out. They're happy to see each other, but don't drop the act and acknowledge that she's Ji-hyun - rather, they return to how they were before, with Kang knowing the truth but pretending she's Yi-kyung. (Even though he knows the truth, she's still banned from acknowledging her true identity, and she feels that if she gets too comfortable with him, she'll forget herself and make mistakes.)
She has family matters to take care of today, so she promises to report for work tomorrow, and he promises to pick her up in the morning.
Yi-soo shows up while Ji-hyun is grocery shopping, and gets all cutesy with her before she sets him down with the reminder that she's Ji-hyun. He grumbles that his sunbae is testing his patience on purpose (lol), then slyly comments on her own melo-loveline with Kang - and forbids her from any skinship while she's still in Yi-kyung's body. Haha. Ever the possessive boyfriend, eh?
