BTOB asked fans to send in questions for Changsub's birthday!
Changsub is turning 27 (26 internationally) on the 26th, and fans were asked to send in questions during 21st-23rd to their official Twitter. Out of all the questions, Changsub is going to pick a few and answer through his own handwriting.
As a small bonus perk to fans, the tweet was made at 2:26 PM in Korea, which is considered 'Changsub o' clock' as it's his birthday in time form.
Will you be tweeting your question to BTOB?
