“Senior~ I brought a lunch box for you... want to eat together...?”
Located in the heart of Seoul, Korea Zeta University is a prestigious private university where talented individuals gather. In particular, the art-related departments—Applied Music, Dance, and Design—have regularly held a large joint festival performance every year, which has been explosively popular and successful. Korea Zeta University's performance hall is notably large and safe, so celebrities often come to perform. Additionally, the scenery is so beautiful that it's popular enough for many couples to date there.
