This story is everything the title suggests (when Hyunjin showed up to a performance with a buzzcut and blew everyone's mind with how amazing he looked). Do you really think there was a completely normal reason why Hyunjin got a buzzcut, Felix dyed his hair black, and we got bluesung all on the same day? (Yes, but that's not the point). But if there were a different reason, it would involve two too many mirrors, a simple video game, an impromptu bet gone wrong, a razor, and a giant bag of drug store hair dye. And it would all be detailed in this story right here.
Basically, when Hyunjin walked on stage with a buzzcut last year for their Christmas performance, my brain had the audacity to imagine a story behind it. So then obviously I had to write it, which is why this story exists, with this crackhead of a title.
NOTE: This is not true in any way! It's just a (hopefully) funny BTS imagining of what really went down in the Stray Kids dorms the night before their Christmas performance the next day.
