Coming across Wook after he dropped his books Seo merely glanced at him before walking away. Observing Wook and Eon he asks the former how he is and suggests next time for them to eat together. Enjoying listening to classical music, Seo is also good with knife tricks. He is curious as to why Eon is interested in Wook. Approaching him in class Seo happily shares that he is also a returning student. He was not feeling well so took a year off. Answering that he is fine now, Seo then questions where Wook's dad is. What he means is Wook's brother's company, the Ilkang Group, belongs to his family. At seeing Eon, he chooses that moment to suggest he and Wook have lunch together and for him to bring snacks.
