It turned out that Um Ki Joon and Han Eun Jung were former lovers.
On the 5th episode of KBS 2TV Wednesday/Thursday drama "Golden Cross" broadcast on April 30th, Michael Jang (played by Um Ki Joon) and Hong Sara (played by Han Eun Jung)'s relationship was drawn out.
On this day, Michael Jang started to pour out anger to Hong Sara because of Suh Dong Ha (played by Jung Bo Suk) and Suh Dong Ha talked about Kal Sang Joon (played by Park Byung Han) that was pushed to a risk.
Kim Sang Joon saved his life thanks to Michael Jang after almost dying because of the actual criminal underlying the Chundamdong real daughter murder incident because of Suh Dong Ha.
Michael Jang ordered Sara Hong after saying that it would be necessary to find out who the person was that saved them.
As Hong Sara wanted to receive an order and leave, Michael Jang asked, "Do you want to sleep over?" Hong Sara refused at once saying, "I don't eat cold rice." At this, Michael Jang said, "Oh we're no longer hot" showing that the two used to be lovers in a past life.
