Big Star's FeelDog let go of the swag he showed in the "You Got Some Nerve" music video for a cuter image to share with fans on his 21st birthday (International age: 20)!

On the 27th KST, FeelDog shared on his me2day, "Yesterday with Big Star & 'A Bit of Love' team! I received a surprise birthday party and gifts from them, and although I couldn't spend it with ONLY ONE, I received your hearts, so I feel like I'm flying keke. Though I lack in a lot of aspects, I will work harder to show an improved version of myself. ^^ Thank you~ Today is the live broadcast of 'A Bit of Love'! My first line will appear today! Euh ak~ I'm so nervous~?? I'm very embarrassed, but I will unveil myself wearing a high school uniform to our ONLY ONE for the first time.^^."

The idol star surprised fans with his 180 degree transformation from a hip hop artist to an ordinary high school student in his uniform.

Netizens congratulated him on his birthday, commenting, "Happy birthday to our leader", "I can't wait to see you act", "You were a hip hop artist yesterday, and now you're a student", and more.

FeelDog recently joined forces with idol rappers B2ST's Junhyung and EXID's LE as well as hit-making producer Brave Brothers for the daring single "You Got Some Nerve".

Happy Birthday, FeelDog!
