woonggi was in one recently but i cant think of the name

ZEROBASEONE - Jiwoong (Kissable Lips, Roommates of Poongduck 304)

DKZ - Jaechan (Semantic Error)

Former The Boyz - Hwall (Color Rush)

VIXX - Hyuk (Color Rush 2), Leo (Happy Ending Romance)

A.C.E - Junhee (Tinted With You)

SPECTRUM - Jaehan (A Shoulder to Cry on)

OMEGA X - Yechan (A Shoulder to Cry on)

OnlyOneOf did, I believe!

not a bl but moonbin (rip) did play a gay character in the drama moment at 18

Jiwoong

Got7 Jinyoung, Twice Dahyun, Blackpink Jisoo, and Astro Cha Eunwoo

I feel like Cha Eunwoo has to be one of the most prime examples of this. Very successful household name as an actor and whatever else he's doing at any given time, more well-known than Astro at this point, and still active in Astro and very dedicated to the group (as far as this non-Aroha knows, I'm not too familiar with them).

BTOB Sungjae

Jinyoung

SHINee Minho (Key and Onew have also done some acting but aren't in as many Kdramas as Minho)

Most Exo members (D.O. especially)

Red Velvet Joy and Yeri

IU (solo)

Ok Taecyeon (2PM)

Suzy (Miss A)

Park Hyungsik (ZE:A)

Jinyoung (GOT7)

Yoona & Seohyun & Sooyoung(GG)

Seolhyun (AOA)

Suho & D.O. (EXO)

Rowoon (SF9)

Siwan (ZE:A)

Minho (Shinee)

T.O.P (BigBang)

Sungjae (BtoB)

Kwon Nara (Hello Venus)

Krystal (f(x))

Seo Inguk (solo)

These are the ones I can think of immediately

Edit :- added 4 more

Edit :- edited out V cuz yes can't judge him yet

Seventeen's Jun!! He's recently starred in a film with THE Jackie Chan.

Well he is still successful through squid game (if not through his other acting gigs) since OP asked for ones that are successful i mentioned him (regardless of his PAST).

Edit :- And other Factuals the VIPs have explained 👇🏻

EXO's D.O.

Yeah that's why I didn't include him in the main list (rather did in an edit) but he sure created buzz during that time.

Though Hwarang wasn't my cup of tea he did considerably well ig.

Along with what u said i would really like to see Jin do an acting gig 🙏🏻

He's busy promoting Squid Game this week. Netflix treats him like he's the main character. He even filmed Netflix K-Content ads with Martha Stewart.

Park Jihoon (ex Wanna One) is getting a lot of recognition for Weak Class Hero atm.

TOP's not "being" cancelled. He "was" cancelled. For smoking weed like what... 2 times? In an incident that happened close to 10 years ago. Squid Games is his return to form. He's doing amazing right now. He's practically one of the most famous cast members out of all the SG cast right now.

Kim Sejeong, She's excelent as a singer and as an actress!

Hyuk, Leo, & N from VIXX all have been cast in gay dramas. Jaehyun from NCT was supposed to be in one, but the drama was cancelled.

Seoham (ex-KNK) and Jaechan (DKZ) both acted in Semantic Error and were the main protagonists (awesome drama if you haven't watched it!).

Park Junhee from A.C.E is the lead in a BL called "Tinted With You". I find the writing kind of eh, but his acting in it is excellent.

Can't believe Jiwoong (ZB1) hasn't been mentioned yet lol

Yechan and Jaehan from Omega X starred in a Shoulder to Cry on. Hangyeom from the same group starred in Jazz for Two.

One of my absolute favorites is Park Hyungsik who debuted as an idol with ZE:A (along with Im Siwan and Kim Dongjun, among others). He was my bias in ZE:A, too. And while they didn't particularly flourish as idols due to S-word Empire, he's been acting up a storm. I'm so happy to see him back and active in dramas since his enlistment finished.

And of course, I also love Eunwoo. People might think he's a one-note actor, but he's actually not. I'll leave it at that since his acting has always been highly controversial and I'm not really up to debate about it. :)

2PM's Taecyeon and EXO's D.O!

EXO DO and Got7 Jinyoung.

DO is a natural and is soo talented, his first drama it’s okay thats love was so amazing

Jinyoung’s drama he is phsycometric is so good and his crying scene broke my heart.

He’s my fave too, I think he also picks really good scripts and is super good looking. I first watched him in what happens to my family a popular weekend drama and he was so cute and I have since watched him in all his dramas. I think in korea he’s more known as an actor now.

I used to never think much of IU as an actor cause I found her acting to be mostly kinda bland but 'My Mister' changed my opinion so drastically. She was absolutely fantastic in that drama!

BTOB Sungjae!

Sieun of StayC was a teen actress and played the younger version of female leads in a lot of dramas in the last 5 years or so.

Lee Know from Stray Kids was a professional dancer and was one of BTS's back dancer.

solar from mamamoo trained to be a flight attendant before becoming a trainee at rbw

nct’s chenle was a solo artist in china and released three albums before debuting in nct dream

Jackson was an Olympian in the Youth Olympics (fencing)

• Choi Ji Woo - Winter Sonata, Stairway to heaven, Date w/ Tiffany (didn't watch The Truth)
• Lee Young Ae - Jewel in the Palace
• Song Hye Kyo - Autumn in my heart, Full House, Hotelier (little bit of My Guardian Angel)
• Chae Rim - All About Eve
• Lee Da Hae - My Girl

Who is the last girl?

Kim Jung Eun of Lovers in Paris was popular in our country back then.

Stairways to Heaven starring Choi Ji Woo was the BLUEPRINT for kdramas. That drama explored every trope you can think of! Lost memories, forgotten identity, evil stepmom and stepsis, handsome chaebol fiance, studying in america overseas, childhood sweethearts, car accidents, tragic ending, cancer, love triangle, poor girl-rich man, etc!

I watched it religiously as a kid! Lol.

Yes I am a fan even after not knowing any of these icons >.<

Not all but there's a few members who are more famous than the group, ZE:A.

Im Siwan Park Hyunsik Kwanghee

Probably but I wouldn’t really count them since that was the sole purpose of these groups, to bring together the most popular members from their respective groups to make a super group instead of them becoming bigger than the group if that makes sense :]

Maybe sf9 ive heard they're all doing well from themselves as actors to the point of being more known for that

15& was a duo under JYP which included Jamie (Park Jimin) and Yerin Baek. Both of them have become far more successful and well known after leaving JYP and going solo, Baek Yerin especially has a pretty great little niche in indie music carved out for herself (please listen to tellusaboutyourself if you haven’t already, one of the best albums of 2021 from any genre) but Jamie has certainly done a good job especially as a features artist.

I bet your answer could also be found in the super nugus. there was a group i saw that was made up of twitch streamers and if i had to guess id bet theyre all more popular as streamers than in their temporary group. I dont even remember their name at this point so i know this isnt a very helpful answer.

Except for siwan, kwanghee, and that one guy who looks like han gain, idk who the other members are.

Edit: mixed up the GaIns
