"Angel Eyes" Koo Hae Sun found Lee Sang Yoon's letter that Jung Jin Young had hidden.
On the episode of SBS weekend drama "Angel Eyes" broadcast on May 11th, Soo Wan (played by Koo Hae Sun) wanted to get a gift for Jae Beom (played by Jung Jin Young)'s gift for Parent's Day and went to Jae Beom's study.
On this day of "Angel Eyes" Soo Wan finds in Jae Beom's desk the U.S. address that Dong Joo (played by Lee Sang Yoon) had left for him. Jae Beom had hid this the whole time.
Soo Wan was in shock and asked, "Why did you do this?" Jae Beom said, "I thought it'd be better to not let them know about this. You were missing them so much. I didn't want to give them the pain of not being able to meet someone that you liked. I thought it'd be forgotten as time passed."
At this, Soo Wan said, "What right do you have to make such a judgment. How did you think to con the daughter for more than ten years" and was angered. Jae Beom said, "You two each have your own way to go. You and Dong Joo are my kids too. I want you to be a little less hurt and wanted you to live a fabulous life" as he listed reasons that Soo Wan couldn't understand.
Soo Wan who heard this said, "I don't know why you're doing something as severe as this" and ran out of the house. At this, Soo Wan read the letter that Dong Joo wrote. In the letter, there was the heart of Dong Joo that was thinking about Soo Wan and Soo Wan cried.
