Overview

• The main poster features Kim Da Mi and Shin Ye Eun’s characters out of uniform, framing a fleeting moment of youth beyond Route 100.
• JTBC released stills and profiles for four supporting bus attendants—played by Lee Min Ji, Park Ye Ni, Oh Woo Ri, and Jung Bo Min—who share dorm life with the leads.
• Character notes depict a strict dorm leader, a warmhearted ‘swearing pacifist,’ a quick-witted yes‑woman, and a deceptively clumsy youngest roommate.
• The production team says the attendants’ banter changes the show’s atmosphere, with performances intended to evoke the spirit of 1980s youth.
• A new teaser centers on the heroine’s budding first love, building momentum toward the September 13, 10:40 p.m. KST launch.
