It turned out that in "Angel Eyes", Kim Yeo Jin's death was related to Jung Ae Ri.
On the episode of SBS weekend drama "Angel Eyes" broadcast on May 11th, Young Ji (played by Jung Ae Ri) started to reminisce about the past.
On this day, Young Ji started to look into the background investigation and identity of Dong Joo (played by Lee Sang Yoon). He checked that the cataract of Soo Wan (played by Koo Hae Sun) was of Dong Joo's mother Jung Wha (played by Kim Yeo Jin). In the past, the person who had put medicine into Jung Wha by dissolving it in water was Young Ji.
Afterwards, Young Ji required Ji Woon (played by Kim Ji Suk) to separate with Soo Wan. Young Ji said, "Whether it's a marriage or engagement, just give it all up. Just cut off the whole Soo Wan matter." Ji Woon said, "Why are you doing this all of the sudden?" and was in awe.
At this, Young Ji said, "You're the one that is being ruined. Do you need a more definite reason? I don't like Soo Wan. I can't be okay with someone like Soo Wan who has such bad luck from entering into my hosue. Let's give it all up" and threatened him to cut off a relationship between Soo Wan.
