On the January 6th broadcast of Mnet's 'Music Triangle', 4men and their singer-turned-producer Yoon Min Soo featured as guests together for the first time.

Yoon Min Soo shared, "4men's nickname 'music chart kings' follows them around, and it's the same this time as well. 'Hello It's Me' has been receiving a lot of popularity right as it released."

When asked, "What do you think is 4men's secret to their popularity is as a producer?" The producer revealed, "We make an effort to cover our true stories to the best of our ability and write lyrics that are honest. But more than anything else, I think 4men's tone of voice and singing ability are the secret. Because they sing well, no matter how bad of a song I produce, they can sing and take in the song well."

4men recently released their 5th album 'The True Story', which ranked high on real-time charts immediately upon its release. The title track "Hello It's Me" is also receiving attention for portraying the true story of Yoon Min Soo.
