Rising to fame through the survival show I-LAND, Heeseung debuted with ENHYPEN under Belift Lab in 2020 as the group’s main vocalist and center. His vocal ability shines through his soaring high notes, including his excellent pitch control and stable live singing, making him one of the standout vocalists of the fourth-generation idol scene.

Many fans also believe he deserves to be officially recognized as a main dancer, thanks to his precise and powerful execution of choreography. However, what truly elevates him is his creativity behind the scenes. He became the first ENHYPEN member to be credited as a producer, showcasing his songwriting and composing sкιℓℓs in tracks such as “Highway 1009” from the 2024 album “Romance: Untold,” co-written with other members, and contributing to “Bite Me” from the album “Dark Blood.”

Often regarded as ENHYPEN’s “ACE,” news of his departure from the group in March 2026 left both netizens and fans ѕнσ¢кed and initially struggling to accept it. Notably, despite leaving the group, he will continue his activities as a solo artist under Belift Lab. In terms of his connection to BTS, this also means he remains a junior artist within the same ecosystem as the global K-pop superstars.

In this context, a video capturing Heeseung’s thoughts about his senior during a fancall quickly drew attention—particularly regarding which BTS member he would most like to collaborate with.

Specifically, on the 23rd, a fan shared a fancall clip with Heeseung. When asked, “When are you going to do a collab with Jungkook?”, the singer reacted with surprise and asked back, “Jungkook sunbaenim?”, before replying with both hope and hesitation: “I hope so… I hope to but… he’s really busy.”

Although his response was brief, the way he referred to him as “sunbaenim” and his careful choice of words clearly conveyed the respect and admiration Heeseung holds for his senior.

As soon as the fancall clip began circulating, fans of both artists expressed excitement at the possibility of a future collaboration. Many believe that with Heeseung’s vocal tone and performance style, a collab with Jungkook could create remarkable “chemistry.” Meanwhile, ARMY were equally thrilled to see a junior artist openly showing genuine admiration for a BTS member.

In fact, this is not the first time Heeseung has expressed his admiration for Jungkook. Longtime fans are well aware that he has always viewed Jungkook as a role model in his career. In an interview, when asked about his biggest musical influences, Heeseung shared: “I’ve always looked up to Jungkook, who has been my role model ever since my trainee days.”

Beyond words, Heeseung has also shown his interest in Jungkook’s activities on multiple occasions. During a livestream with Beomgyu, both HYBE juniors repeatedly praised Jungkook’s gaming sкιℓℓs. Notably, Heeseung even suggested that Beomgyu watch Jungkook’s Overwatch gameplay videos from his livestreams with fans late last year—showing that he keeps up with his idol just as closely as any fan would.

Although both Jungkook and Heeseung are currently busy with their individual schedules, the mere fact that Heeseung has openly expressed his desire to collaborate is enough to spark excitement among fans. Social media has since been flooded with reactions such as:

- We need to lock them in a recording studio NOW. That would be the best collab of all time trust

- OMFG!! THIS NEED TO HAPPEN!!!! We will wait for that time Heeseung

- Their voice would perfectly match together. A collab I would d1e for oh my god please
