Lee Junho's story about having a fierce fight with his members during his 2PM days

It is surprising to hear that Lee Junho honestly confessed that he once had a huge fight with the members during his time with 2PM, even using profanity. Given that they have worked together for a long time, there must have been moments when their opinions clashed, but this behind-the-scenes story is quite different from their public image, so it makes me even more intrigued. I would love to hear the detailed story he shared on 'Cold-terview' about what exactly caused their emotions to become so heated back then.
