On the episode of KBS 2TV Wednesday/Thursday drama "Pretty Man" aired on January 8th, Ma Tae (played by Jang Geun Suk) found the password that his mother left. It was Bo Tong (played by IU) who was always next to Ma Tae).
Ma Tae went to Bo Tong's house and while Bo Tong was out selling roasted chestnuts, he talked to Bo Tong's mom. When asked what kind of son-in-law she wanted, Bo Tong's mom said, "Just someone who can make my daughter happy. Someone who can make her smile forever. Your mom probably thought the same" as she shared her thoughts.
At this, Ma Tae suddenly thought of CEO Park Ki Suk (played by Dok Ko Young Jae)'s words, "Ma Tae, for your happiness, it's so important." In addition, he remembered that Bo Tong had met CEO Park Ki Suk before his mother died and Ma Tae realized the password was Bo Tong.
Meanwhile, Ma Tae found Bo Tong who bought roasted chestnuts and Bo Tong begged, "I was late going to the market on a bus. Please eat this." Ma Tae sees that Bo Tong had gone heads over heels to find roasted chestnuts and thought about how much she had given up for him. At this, Ma Tae feels so much emotion that he hugs her and was happy thinking, "Mom, that password, it was Bo Tong."
