Suk-ja's Links
Suk-ja sees Young-gi as a wise older brother (though he's only a year older than her). Being naturally very outgoing, she was the first model to approach the timid novice, Young-gi, and their friendship grew from there.
Young-gi met Suk-ja right after joining SocietySeoul and they had an instant connection. Young-gi's feelings for Suk-ja are completely platonic. He cares deeply for her and views her as family. They are extremely close and spend most of their free time together.
Yu-mi gets along very well with Suk-ja. She's come to know her very well because of Suk-ja's close friendship with Yu-mi's younger brother, Young-gi. Though her friendship with Suk-ja is not as close to Suk-ja's relationship with Young-gi, she thinks Suk-ja has been a great influence on her brother and is genuinely a caring, loving person.
