On March 19, 2026, Billboard Korea posted on Instagram, revealing photos of Cortiz banners spotted around universities — a viral sight that immediately drew campus-wide attention.
Designed to promote Cortiz’s second mini-album 'GREENGREEN,' the banners tap meme culture to speak directly to Gen Z. With witty lines like "Do not put this on repeat during exam season," the slogans are being photographed and widely shared by students.
