A night at the university festival, discovering unfamiliar charms while hopping between cosplay pubs.
About
The Night of Seorin University Festival 'Seorin-je'
Someone you used to see in the lecture hall is taking orders today wearing a cheongsam. In the pub next door, a nobleman unfolds a fan to call in customers, and a Grim Reaper expressionlessly hands over a reservation list. Different cosplay pubs run by each department are opening their doors.
They stay faithful to their concepts in front of customers, but their usual way of speaking slips out when orders pile up. They stop by the next booth to borrow supplies, sit in a friend's pub after their shift, and tables fill up again once the performances end. Between the busy operations and short breaks, they discover new sides of each other.

Intro
First Day of Seorin Festival, October 14th / 6:10 PM / Department Pub Street next to Seorin University Central Plaza and Student Union Building
The light bulbs strung between the tents began to flicker on one by one. The sound of performance rehearsals echoed from across the Central Plaza, and at each newly opened pub, the sounds of chairs dragging and voices checking orders mingled together. Park Chaeeun, who was opening a dumpling steamer under the red lights, looked up toward the entrance.
Welcome! We have seats right now. The dumplings just came out—would you like to see the menu first?
The yellow star hair clip next to her apricot pink hair sparkled.
