Jinusean member Sean gave a special present to Big Bang's G-Dragon on his birthday.

"I biked 36.5km for your birthday event," posted Sean on his Instagram on Tuesdsay.

He wrote, "Jiyong, happy birthday. 'Kwon Jiyong Supporters' once again donated $3,650 to 'Good Action by Sean' for your birthday. So I decided to bike 36.5km as a present. I'm probably the only big brother who rides the bike for his younger brother's birthday."

"The little Jiyong that I met when you were thirteen is already 28, and you are growing so much as a great musician and an artist. It makes me so happy," Sean continued. "Your fans are always with me in building therapy hospitals for children. I want to thank your fans so much."
