On June 12, the rapper wrote via social media, "The lyrics I wrote years back seem to be leaving many wounded. It is due to the fact that I was young and immature back then. I am deeply repenting at the moment."

The song "Dope Man", released in 2013, includes lyrics about a woman being sexually harassed with phrases like�"Your rap clothes are from the Daegu disaster,"�alarming listeners.

Changmo explained in the apology letter, "The lyrics I had written back then were written in my early 20s when I was still an amateur. Afterward, I had realized my faults and even posted a statement of apology. Many have reprimanded me as a result, and I too am deeply reflecting on my hasty actions."

He expressed, "Furthermore, I would like to sincerely apologize once again to everyone who has been hurt by the lyrics. I will do my best to learn from this experience."

Prior to this, Changmo�also apologized for the demeaning lyrics at the time of the 'Sewol Ferry' tragedy in 2014.

Meanwhile, the rapper received attention in the hip-hop/R&B scene for his song "Maestro" released last year, leading him to collaborate with fellow artists like Suran and�Hyorin.
