The dramatic visuals have raised expectations for the full music video. Fans will be able to see how the storyline develops when the complete version arrives.
H1-KEY’s Journey Before the Comeback
H1-KEY debuted in 2022 and gradually developed a reputation for its distinctive musical identity.
Songs such as “Rose Blossom,” “Time to Shine,” and “To. My First Love” helped introduce the group’s emotional and energetic style to a wider audience.
In March 2026, the group released LOVECHAPTER, a seven-track mini-album built around the theme of first love. The project continued H1-KEY’s interest in storytelling and youthful emotions.
