In the latest episode aired June 26th, Jang Ma Ri(Suzy) expressed her feelings about the way Kyung Joon who is in the form of Seo Yoon Jae is acting towards her.
She dropped huge tears and said, "Kyung Joon is mad at me. It is because I lied again. Because I put teacher in danger so he is mad at me. I didn't do it on purpose. Kyung Joon doesn't like me because he blames his mom's death on me."
And with this said, she reveals the truth behind the death of Kang Kyung Joon's mother, "My dad was going to propose to Kyung Joon's mom but I did not want that to happen so I lied to my dad. That day, she got shot and passed away. If she came to see my dad, it wouldn't have happened... it is all my fault."
Now we know that Jang Ma Ri and Kang Kyung Joon lived in America together and they were both worried about the remarriage between the two parents so made a plan together to stop it. Jang Ma Ri told Kyung Joon, "My dad is proposing to your mom today. Stop your mom from coming over and I'm going to tell my dad that I am sick." Hearing this, Gil Da Ran sympathizes for crying Jang Ma Ri.
After Suzy's confession, Kang Kyung Joon also expressed his true sad feelings, "I did not want my mom to marry a different man. I was whining like a little child which stopped me from seeing my mom ever again."
