Jin actually made a big mistake during their first performance at M! COUNTDOWN. It was his first time wearing a microphone pack and went up on stage with them attached to his pants, but it turned out to be too heavy. During " We are Bulletproof pt.2", there is a part when they jump down, but while doing so, his pants went down all that way to his thighs. He then quickly pulled them back up but they fell off again during the second time.
