This work is the third lead single from the much-awaited 2nd EP. The title ``220'' means ``Second to none,'' meaning ``second to none.'' Smartt, who struggled without being appreciated, says, ``Thanks to my colleagues and seniors, I was able to shake off my weak self.''Based on his own experience, he gives encouragement to those suffering from similar situations and to himself in the future. It is a song that spells out. The guest performance included PVCMVN, a bilingual rapper born in 2000 who has released many hit songs such as "#EverydayAsobi[REMIX]" and "sunlight (feat.ANDY)" and is popular among the SNS generation.
