Kang follows the sound of Ji-hyun's song, and it's the last straw that puts him over the edge. He walks up to her at the piano and asks, "Who are you? Are you...Ji-hyun?" Ji-hyun's mouth opens, unable to hide her shock. She stammers, unable to get a word of protest out.
Her hesitation makes him even more sure of his instinct, though she begins to protest that he's nuts. And Kang knows it's crazy. Except..."You feel like Ji-hyun." He starts shouting all the ways they're the same, and Ji-hyun starts to panic. She grabs her tear necklace (which will break if anyone catches wind of her true identity) and insists she doesn't know what he's talking about.
Manager Oh walks in to see Kang shouting at her, and interrupts them before things get out of hand. He tells Ji-hyun that this piano is the only thing Kang has left of his mother's, and to just consider him being sensitive and acting out because of that.
As they stand side by side with a wall between them, they each think to themselves: Ji-hyun: "Han Kang, how did you know?" Kang: "It doesn't make sense." Ji-hyun: "What if Kang keeps suspecting?" Kang: "I must've seemed like a total crazy person."
He rounds the corner and finds her standing there. She offers up that she must remind him of his friend a lot, and he says that she does...and doesn't too. He then adorably asks her for her phone number, pretending to be cool about it.
He hides his embarrassment by nagging her that she shouldn't make people worry like that, and asks what happened yesterday. She just says she wasn't feeling well, but he adds that he went to her place, but she wasn't home. Ji-hyun realizes that it was Kang knocking on the door last night.
And then, the not-quite-so-bright Ji-hyun puts the puzzle pieces together this way: that Kang was that worried about Yi-kyung, and that noticing her similarities to Ji-hyun made him angry...because he dislikes Ji-hyun. Oh, silly girl. Not that the very simple and direct Ji-hyun would know that Kang's shouting is just masking his feelings. That's just not in her nature. But still.
She goes to see Seo-woo, and gets the rare chance to sit down with her friend and eat some pastries. But Seo-woo keeps turning the conversation to In-jung and the thermos, asking about her mystery boyfriend. Ji-hyun thinks to herself that Seo-woo's already forgotten about her too.
Min-ho and In-jung go out on a date, and she tells him that she's going to quit her job tomorrow. The rumor mill is running rampant that a ghost kept the president from signing his will yesterday, and she doesn't want to be reminded of Ji-hyun anymore.
Meanwhile Dad collapses, and Ji-hyun shows up at the hospital soon after, planning to play the part of her friend. She sees Dad lying next to her comatose body and cries, assuming that Dad's just exhausted himself from worry.
She comes out into the lobby, tears streaming down her face, which is when Min-ho arrives and sees her. He stops her by grabbing her arm and asking why she's here, and in her head, Ji-hyun thinks to herself that he's daring to come here, in an effort to get that will signed.
She just says, "Take your hand off of me," and walks away. When Min-ho goes upstairs, he finds that Dad is trying to keep his condition a secret from Mom, and decides he has to step in. He pulls her aside and tells her the truth, insisting that Dad needs surgery right away. Ji-hyun has followed him up and sees her mom crying, but doesn't hear what he's said to her.
Seo-woo asks In-jung again about her secret boyfriend, and In-jung freaks out that she's going around asking Yi-kyung about her. Seo-woo confesses to following her out that night, and thinks that her boyfriend looks a lot like Min-ho...but is naïve enough to believe that he just looks like Min-ho, and not the other thing-the backstabby thing.
