Each K-pop group member has his or her own crucial part to play, and it will be hard, no matter what, if he or she goes on leave or withdraws. There are, in fact, some artists who have tougher responsibilities, may it be in writing songs, music production, choreography, and more, which is proof that they will end up making the band suffer if they decided to pull out.

Fans echoed this topic of discussion at a public platform recently and debated which artists would be a huge loss to their groups, and here are results.

SEVENTEEN's WOOZI 

"Woozi is the artistic and musical image of Seventeen. He also obviously is after both sides, Seungkwan and DK, the best overall vocalist in the band. Therefore, he moves really well and is an adorable member of the party."

PENTAGON's HUI 

"He showcases in all their album tracks and stages, both vocally and in terms of production. The first individual I consider is Hui of Pentagon." 

MOMOLAND's JOOE AND NANCY

"For Momoland, it'll be JooE and Nancy (JooE and Nancy) who should be covered at all costs."

MONSTA X's KIHYUN

"It will be a catastrophe if Kihyun took time off from Monsta X. The backbone of the band is his voice and their complete discography."

EXID's LE

"Some participants can be delegated by other members (including when Solji leaves for therapy, although it was hard to do), but EXID certainly can't be the same without LE." 

(G)I-DLE's SOYEON

"The very obvious thing for me is (G)I-DLE without Soyeon because she does a lot and is their primary rap artist." 

STRAY KIDS' BANG CHAN

"I think that the obvious response to Stray Kids is Chan. While the band might be covering his tracks (he appears to be in the top end of line allocations, although he isn't the only competent vocal player in the band, obviously), but because he's written and/or credited on nearly all their tracks."

ITZY's YEJI

"I thought Itzy would've been strange if lacking Yeji. Although Lia is the lead singer technically, I feel that Yeji is more attached to her vocals because the tracks of itzy have seemed to fit a little more easily inside her range than Lia's."

CLC's YEEUN

"Yeeun of CLC. She appears to be a core of your concept of a teenage crush. Without Yeeun rap drop (not High Heels included) I honestly can't imagine a CLC."

RED VELVET's WENDY

"I love the voice of Seulgi, but you might claim that the exposure of certain pieces of Wendy is a challenge to her. If SM did a track for a Wendy-less RV, it might sound very different, perhaps not so dramatic as others, but it would be very remarkable."

WINNER's YOON

"I believe, Winner without Seungyoon. That's what the group itself said because SY's trying to cover everyone else, but the others don't truly cover him." 

NCT's MARK AND TAEYONG

"Taeyong and/or Mark of NCT 127. Many of the stuff from their previous styles are so different that they would sound strange without their extra popular tunes, such as Regular and Cherry Bomb."

EVERGLOW's MIA

"Mia from EVERGLOW. She is their lead singer and main dancer."

TXT's YEONJUN

"Without Yeonjun, I assume TXT (currently). Today, he makes more than half his rap lines and appears to be their best rapper technically (so far).

Despite a lack of regular statements, Big Hit seems to want him to be considered the core of the band, particularly with his appearance on stage. He seems to keep the others, in general, during the promotional period, together as the eldest leader.

He's almost always the one who leads everybody to make their formal greetings on the camera."

TWICE's NAYEON AND JIHYO

"TWICE Nayeon and Twice Jihyo.

TWICE is a really solid squad, but their downside is, instead of being a conventional idol group, this is a group of practically the same equal members.

JYP was very clever because he wished to have two members focus on their strengths and that those strong points accommodate for the weak spot of others, particularly as half the group is composed of foreign artists.

It's also a weak point since the highly skilled groups / main vocals carry the band. Contrary to other groups where the company helps to ensure that every idol is on an equal footing."
