Moonbin’s Enduring Influence in K-Pop
Moonbin wasn’t just a performer; he was a beacon of warmth. Debuting with ASTRO in 2016, he captivated fans with his dance moves, vocals, and genuine kindness. His journey began as a child actor, notably in Boys Over Flowers (2009), before he transitioned into a K-pop idol. Known for his close bonds with fellow idols, Moonbin’s “98-line” friendships with SEVENTEEN’s Seungkwan, VIVIZ’s SinB, and others were legendary. His passing on April 19, 2023, at age 25, left a void in the industry. Fans, known as Arohas, and artists alike continue to honor his memory through music and heartfelt tributes.
The release of Moon underscores his influence. The song’s lyrics, penned by ASTRO members and former member Rocky, weave personal memories into a touching narrative. It’s a testament to how Moonbin’s spirit still inspires creativity and unity among his peers.
The Tribute Song ‘Moon’: A Collaborative Masterpiece
The Moon project is a star-studded affair. Here’s a breakdown of its key contributors:
- ASTRO Members: MJ, Jinjin, Cha Eun-woo, and Yoon San-ha poured their hearts into the track.
- Moon Sua: Moonbin’s sister added a deeply personal touch.
- Other Idols: VIVIZ, MONSTA X, SEVENTEEN, Stray Kids’ Bang Chan, SF9’s Chani, and more lent their voices.
- Purpose: Crafted as a “letter” to Moonbin, it aims to comfort grieving fans.
Cha Eun-woo spearheaded the project, reaching out to Moonbin’s friends to create something meaningful. The teaser for Memory of the Moon, released on April 16, 2025, showed artists in the studio, their emotions raw yet hopeful. Fans on X called it “precious,” with posts like, “We hope you’re smiling the brightest up there, Moonbin” (

Mixed Fan Reactions: Love, Grief, and Controversy
The release of Moon wasn’t without controversy. While many fans found solace in the song, others voiced concerns. Some felt ASTRO’s upcoming concert, which includes former member Rocky and a Moonbin tribute, used his name for publicity. A Koreaboo report noted fans saying it “looked like they were using the deceased as a shield.” These sentiments reflect the delicate balance of honoring a loved one in the public eye.
On the flip side, fans who embraced Moon saw it as a healing gesture. The song’s release coincided with Moonbin’s second death anniversary, a day already heavy with emotion. Posts on X, like
@skzpopbase’s, highlighted Bang Chan’s contribution and the lyric, “Welcome me with a smile at the door of my dreams.” This duality—grief and gratitude—shows how Moonbin’s memory continues to unite and divide.
Moonbin’s Broader Legacy: Tributes Beyond ‘Moon’
Moonbin’s impact extends beyond this single. In 2024, Jinjin released Fly, a track he co-wrote with Moonbin, for the first anniversary of his passing. Cha Eun-woo and SEVENTEEN’s Seungkwan also honored him with solo tracks, Stalker and Dandelion. Moon Sua paid tribute at Billlie’s 2024 fan concert, saying she wanted to show her stage to her brother. These acts reflect a collective need to keep Moonbin’s spirit alive.
His 27th birthday in January 2025 saw ASTRO members sharing emotional posts. Cha Eun-woo’s Instagram note, “I miss you even more than usual,” broke hearts. Fans also created “Moon’s Space” at Gukcheongsa Temple, a memorial for Arohas to leave letters. These efforts show how Moonbin’s warmth still resonates.
Why Moonbin’s Story Matters Today
The K-pop industry is no stranger to loss, but Moonbin’s story hits differently. His friendships, talent, and sincerity made him a bridge between groups and fans. The Moon tribute, despite its controversies, reminds us of the power of music to heal. It’s a call to cherish those we love and to find light in darkness.
For Arohas, the song is a bittersweet gift. It’s a chance to grieve, celebrate, and remember a star who became a moon in the sky. As the industry moves forward, Moonbin’s legacy—his laughter, his dances, his heart—will continue to inspire. Let’s hold space for him, not just today, but always.
