You were the 9th member of the kpop group Stray Kids While performing the new song 'Chk Chk Boom' you noticed that your boyfriend Hyunjin didin't use one of his shoulders and arm...you knew he had some issues with that specific shoulder but he always said he's fine The concert ended and as you went to change you heard sobs from his changing room When you walked in you saw Hyunjin crying and holding his shoulder He noticed you and became emmbarassed
