Cha Ji Soo (played by Im Se Mi) is perhaps the most ill fated character on Goodbye Mr Black. She’s jerked around by Min Sun Jae (Kim Kang Woo), who uses her as a toy to over tossing Cha Ji Won (played by Lee Jin Wook). As daughter of a chairman, Ji Soo lives the pampered life. Along with mansions and maids, her outfit reflects her finer way of living. Notice that she always wears white colors. It reflects her purity with all the crime happening around her.
This is Cha Ji Soo before her life was turned black. Her hair is styled, unlike in the later episodes when her hair is straight, untreated. She wears fanciful ruffles and chic blazers. It reflects her stress free life.
Her night dress has a lining that is similar to lining on children’s school uniforms. This reflects that Ji Soo never really grew up. She has been sheltered from the ugliness of the world. Yes, she was blinded by Min Sun Jae (played by Kim Kang Woo) when she overheard him confessing to killing her father. However, she was immediately rescued by Baek Eun Do (played by Jeon Kuk Hwan) and was hidden in China, away from Sun Jae. She’s always had a guardian in her life; from her father to Cha Ji Won (played by Lee Jin Wook) to Yoon Ma Ri (Yoo In Young). After her accident, she’s needed a literal guardian to guide her way.
