However, Changsub drew criticism from netizens after the number 7 sign in their concert. Netizens think Changsub still recognizes Jung Il Hoon as a BTOB member after the case of using his compensation.
Responding to this, finally Changsub released an Instagram post today (25/01) with a caption saying that he showed this gesture so that BTOB would always be remembered by fans and saved their hearts.
Changsub also added that he will continue to be a better artist and person in the future and thanks the fans who are always with BTOB. (www.kpopchart.net)
