The song has a strong Alternative Rock color, inspired by Coldzy's own love experiences, and opens a new chapter in MEDICINE Era - a passionate personal music project.
The name BLEED means bleeding, a metaphor for deep wounds in love, pain but will gradually heal. The song is about a guy who tried to find a replacement after a breakup, but in the end decided to overcome it strongly because he did not let the person around him put more hope.
BLEED's music has Coldzy's signature Alternative Rock, featuring a powerful drum background and electric guitar that evokes the atmosphere of energetic rock stages.
The BLEED MV exploits the image of a burning bed, a familiar symbol of the album MEDICINE. The fire symbolises the end of a relationship, and at the same time signals the beginning of new aspects of music.


Behind the scenes of the MV, many special memories are marked. This is the first time Coldzy has filmed a separate MV with HURRYKNG, and also the first time he has experienced filming in the rain and performing a real fire scene. The crew prepared for the artificial rain scene but suddenly it rained heavily, leaving unforgettable experiences.
BLEED's big highlight is the presence of rapper HURRYKNG, Coldzy's teammate in Bigteam. Coldzy said he always admires HURRYKNG in both human and music, especially the explosive energy that is very suitable for the Alternative Rock genre.
The rapper born in 2000 was worried that he would have to abandon this song or find a replacement. Unexpectedly, HURRYKNG texted "I'm doing a demo", sent the demo back that day and even accepted to film a joint MV, making Coldzy very happy.
