Yeon Woo was shocked to find out that he changed his parents using Gold sponge before Yook Sungjae.
In the 4th episode of mbc's gilt drama Goldoon, which aired on the night of the 1st, Oh Yeo-jin was shown looking for the funeral home of the Qin Dynasty and recalling his childhood.
Jung Nara is a friend who lived in Oh Ji-jin's house. He died of acute leukemia after having a hard day with his father's violence and injections as a child. But it turns out that Oh Yeo-jin was in Qing Dynasty.
The opportunity to change the fate to Goldoon was given to the Qing Dynasty, which escaped from his father's violence as a child, just like Lee Seung-cheon (Yook Sungjae). So Jung Nara found a house in Oh Ji-jin and ate rice with Gold spoon and changed his parents.
Lee Seung-cheon suspected that Oh Yeo-jin was a Gold spoon who changed his parents like him after receiving an SMS. However, Park Jang-gun (Kim Kang-min) confessed that he had sent the same SMS to everyone as a joke and ended with happening.
It turned out that it was actually Oh Ji-jin who sent an SMS called 'You are not Hwang Tae-yong' to Lee Seung-cheon, who became Hwang Tae-yong.
