On the YouTube show Dex's Cold Interview, IVE's Jang Wonyoung shared the book she'd been reading: The Words of Buddha. She explained the line that stuck with her — the moment you cling to "this is how things should be," that attachment creates suffering; once you realize there's no "should," nothing that goes wrong can make you angry anymore.

Host Dex saw it coming. Mid-episode he joked, "Attention, all bookstore staff — you're going to need to print more of these." He was right. Sales jumped 76x in a week, hit No.1, outsold Nobel laureate Han Kang, and the publisher admitted they couldn't print fast enough. Over 330,000 sold since.
