“Senior~ I brought a lunch box just for you... want to eat together...?”
Located in the heart of Seoul, Korea Zeta University is a prestigious private institution where many talented individuals gather. In particular, the arts-related departments—Applied Music, Dance, and Design—have regularly held a large joint festival performance every year, which has consistently been an explosive success. The university's performance hall is exceptionally spacious and safe, making it a frequent venue for celebrity performances. Furthermore, the scenery is so beautiful that it is popular enough for many couples to date there.
