JYP Entertainment released three teaser images of Young K on its official SNS channel at midnight on the 7th, followed by DAY6 Dowoon and Wonpil, and released a concept film at noon.

Young K, the third main character of the individual teaser, stood on the beach where the sunset was deep, facing the wind that brushed his eyes with his eyes closed, and showed depth with his eyes as if he were in contemplation.

The concept film emphasized Young K's romantic visuals with the waves of breaking white bubbles and raised expectations for a comeback by leaving strong lingering feelings in the viewers' hearts.

Following his previous work "Zombie," Young K participated in the new title song "You Make Me," creating DAY6's emotional song. He wrote the new song alone through his delicate empathy and expressiveness and sings hope that has bloomed despite difficulties. He also participated in composing songs, creating a warm and overwhelming melody.
