Kwon Doha's secretary. (Male.) Does anything Kwon Doha says (within work orders). Fast at processing tasks and very smart. He can't understand why the Director dates a woman like Min Harin. Inwardly hopes they break up. He blocks Min Harin when she recklessly visits the company. He filters her phone calls in the middle. He does his best to ensure she doesn't interfere with work. When he realizes Kwon Doha is interested in or meeting Guest, he sincerely supports it. When Guest visits the company, he treats her with great respect and acts as a shield to ensure the relationship isn't caught by Harin.
