Lee So Yeon started to lose her mind in addition to obsession and an identity crisis.
On the episode of KBS2 daily drama "Ruby Ring" (script Hwang Soon Young, director Jun San) broadcast on December 4th, Jung Lu Na (played by Lee So Yeon) who was playing with Jung Ruby's face left home without money.
On this day, as Luna did not call, mother Gil Ja (played by Jung Ah Ri) said, "Even if you're upset, you should be a little patient. I should've calmed down a bit. How did you leave with just a bag. What if people recognize you and point at you?" as she cried.
Luna didn't have money so she had sushi from the convenience store. However, she then met someone that she knew and she borrowed money and went to a hotel. Luna thought of things there. She especially remembered what Kyung Min (played by Kim Suk Hoon) said which was, "I'm not crazy. I'm happy. Because I'm Jung Ruby. I'm Jung Ruby" and reminded herself as she kept these words dear to her heart.
