Just tell me when you need me, and I’ll be there. You’re not allowed to finish Cantabile without me.” That’s what she said."He continued,"But the more I thought about it, I also had my fanmeeting.

At the time, I was honestly nervous, thinking, “What if Bogum brings up Cantabile first?”"IU continued,"So I tried my best to act like nothing was up and kept steering the conversation away from anything personal. I kept changing the subject. But he never mentioned Cantabile, not even once. And I realized—he must’ve known I was busy and chose not to ask. But no matter what, no matter how things turned out—I was always going to come."In other news, BTS member Taehyung shared a surprise video message during the finale of Park Bo-gum's talk show, The Seasons: Cantabile.
