Idols/former idols who participated on dating shows (NOT WGM)?

I don't consider WGM a dating show because it isn't one

Joo Jinwoo

former Produce 101 season 2 contestant, MMO trainee and now solo idol and actor

He appeared on Heart Signal Japan with a season that featured Korean men and Japanese women

thanks to thank, he doubled in IG followers and got some brand deals

he was my favorite on Broduce so I couldn't be happier for him, MMO sucks

Former AWEEK Jeon Eunchan (stage name used to be Ilkwon)

He appeared on the gay dating show His Man

he was one of the fan favorites during the show

he has two YouTube channels now and works as a department store manager

Former Pristin/Hinapia Jung Eunwoo

She appeared on Calm Down My Heart with her best friend (show about whether men and women can be just friends, people who appeared all had at least one half of the pair in love with the other)

Unlike the previous two, she wasn't a fan favorite in the show and even received hate (she started off as the popular pick, but quickly the watchers turned against her and she received criticism on the show especially for the way she treated her best friend who was embarrassingly in love with her, but also for flirting with all of the other men on the show lol, she had them all lined up)

interestingly, Eunwoo appeared on a lot of shows so far, she was on Superstar K4 (as a child, and was eliminated due to cheating on one round), The Voice Kids, Produce 101

Kyla also mentioned her as one of the members who bodyshamed her in Pristin, problematic fave Eunwoo

but fk Kyla because she outed idols to her Discord chat in the past

Quote from vzal

Eunwoo bodyshamed Kyla? When?

Jun.K from 2PM was on a dating show in early 2010s.

Yeah Kyla revealed back in the day that her time in Pristin was a nightmare and that certain members bodyshamed her hardcore and years later revealed who said members were and among them was Eunwoo.

I didn't know that about Jun.K! I keep reading his name as "junk".
