Kim Jaejoong Just Covered a 2000s Classic for His Fans

Summary

Kim Jaejoong just dropped a live cover of izi's "응급실," one of those early 2000s K-ballads everyone grew up with. He titled the video "밥 먹었어?" (Have you eaten?) and captioned it "Happy birthday, Babys" — his fanclub name. It's that sweet, low-key thing where he just shows up on YouTube with a guitar and sings for them.

Why it went viral

Jaejoong's been around since that era himself, so hearing him cover it feels like a full-circle moment. Plus, fans love when idols do these low-key, stripped-down things instead of polished content.
