A campus romance following youths brought together by preparations for the Seorin Festival.
About
At Seorin University, a prestigious private institution in Cheongun-dong, Seoul, youths from different majors and family backgrounds meet through preparations for the Seorin Festival.
From the long-standing academic lineages of the Seorin 'Seonggol', 'Jingol', and 'Line' to the new connections of external students, diverse lives intersect on the same campus.
Classes, assignments, free periods, festivals, drinking parties, clubs, romance, and career worries—though they live their individual lives, they mingle in campus cafes, practice rooms, and on festival stages.
