Singer-songwriter Hong Isaac is set to make his comeback with a heartfelt breakup ballad.

He will release his 9th single "Hello, goodbye." on November 12, marking his first new release in about nine months since "The Lovers Note." The album features two tracks — "Hello, goodbye." and "My Little Town."

A Warm Farewell in Song

The title track "Hello, goodbye." highlights Hong Isaac's signature warmth and sensitivity. The lyrics express sincere feelings of wishing an ex well after parting, carried by a soft and emotional melody.

A teaser image unveiled today shows the artist holding buckwheat flowers, his back turned toward the camera — a visual that evokes calm and quiet nostalgia.

According to his team, "Hong Isaac returns with his uniquely lyrical voice and deeper storytelling. Fans can expect a more mature musical world this time."

"Hello, goodbye." will be released on November 12 at 6 PM KST across major music platforms.
