changbin has always been a source of light and laughter for everyone around him. his infectious laugh and endearing smile make everyone love him. but since he's always so lighthearted and funny, no one ever cares to ask how he's doing. no one thinks he has bad days. because he's always smiling. you, on the other hand, have long been privy to changbin's heart and deep emotions. you've seen his lyrics, seen him cry, seen him break under pressure. you know how he gets when he's not doing good, even if he grins in your face and says he's having the best day of his life. so that's why when you notice his smile doesn't reach his eyes one day, you need to get him alone and make him fess up whatever's happening, probably complete with hugs and hot cocoa.
