Park Yoochun discovers Yoon Eun Hye's identity.

On the Wednesday episode of "I Miss You," Jung Woo (Park Yoochun) finds out that Joy is actually Soo Yeon (Yoon Eun Hye).

Jung Woo, who was tracing the whereabouts of Sang Deuk before he was murdered, sees that Sang Deuk had run into Hyung Joon (Yoo Seung Ho)'s car in front of the prison. He saw Joy become scared at his approach.

This makes him think of Lee Soo Yeon and realizes that it's her.

Jung Woo says, "I'm really late, right? I promised you, let's go to a cafe in Han River." Joy says, "Hyung Joon is coming." But Jung Woo does not stop, "Our promise came first." She tells him that she is getting engaged. He says, "You told me you had already been engaged. How much is a lie? Do you really not like me or are you pretending? Let's date secretly."

He drags her away and Hyung Joon sees that Jung Woo's umbrella had the name tag that he attached to Soo Yeon before.
