IU recently shared some behind the scene moments from her latest music video “Coin.”

While filming her music video, IU revealed to the viewers that she’s never been nervous about filming a music video until filming “Coin.”

I’ve never been so nervous shooting video…It’s the first time I’ve gotten so nervous.

— IU

The reason behind IU’s nerves was because of the special guest cameo featured in her music video. By now fans are aware of the charismatic actor Kim Yoon Seok made a special cameo appearance in the music video!
