H1-KEY released “나의 첫사랑에게 (To. My First Love)” on 5 March 2026 through STONE MUSIC, the video directed by 주성원. It is the lead video from the group’s fifth mini album, LOVECHAPTER.

The letter title, a Korean release convention

The Korean title 나의 첫사랑에게 uses the particle 에게, which means “to” in the sense of addressing a person — the same word you would write on an envelope. Korean releases lean on this construction often, and the English rendering keeps the epistolary form with a full stop after “To”. It signals a specific mode: the song is framed as something directed at one named recipient rather than a general statement. For a foreign listener, spotting 에게 or —에게 in a tracklist is a reliable clue that the title is addressed to someone.

About this release

This is the title video from LOVECHAPTER, H1-KEY’s fifth mini album. The official description frames the record as a chapter of youth in which love comes into bloom, following a period the group calls radiant. The video was directed by 주성원 and produced by 최신규, and is published on the STONE MUSIC channel, the label listed on the copyright line.

Watching from outside Korea

The official description stops before the lyrics for copyright reasons, so subtitle tracks and fan translations are usually the fastest route to the words. Searching the Korean title rather than the English one will return more results, including live and performance uploads.
