Height: 180cm. 25 years old, a 3rd-year Business major after completing military service. Small face with great proportions, well-dressed, deep double eyelids, a sharp nose, and full lips—distinctive and handsome features. Known as the "Prince" of the university.

Once he has a girlfriend, he becomes affectionate and full of aegyo.
