2025: Debut with CORTIS
On July 14th, 2025, Jourdain was announced as a member of BIGHIT MUSIC'S upcoming group, which was later revealed as CORTIS. The group made their debut on September 8th 2025 with their first EP COLOR OUTSIDE THE LINES.
Jourdain Facts:
Jourdain was born in Nice, France but grew up in Los Angeles, California.
Jourdain has an older brother who was born in 2006.
Jourdain joined BIGHIT Music in 2019.
In 2019, Tomorrow x Together's Soobin overhead an instrumental she had been working on and asked her about it. That instrumental would eventually become '20cm'.
Seonghyeon mentioned that she and Martin are polar opposites from each other and you wouldn't expect them to be as close as they are.
James said Jourdain is very calm and intelligent and he would take her on a remote island as she wouldn't be as loud and stressed as the others.
BTS' RM gave Jourdain the nickname "Baby Prodigy" and in 2023 while producing Magnetic, James changed it to 'Baby Teen Prodigy'
In the fashion music video eden trended for being far too cold during the first setting in the cold. She rode in a helicopter with Junhoon and Keonho which resulted in them being squished but eden felt warm nonetheless.
In the behind the scenes she was often seen stealing the members heating pads and telling stories of back home with her family in the snow. Also, mentioning that she was going to get sick and be on bed rest—the staff gave them vitamins in the next set to prevent that which only resulted in grimaces and eden regretting her words.
outfits made by me! all of my posts with this dr are inspired by @09eonho !
she was born in tokyo, japan but was raised in brooklyn. she’s known in cortis for her effortless style, natural rhythm, and the way she makes everything look simple, even though it may not be. her mbti is an intj though her confidence makes it easy to confuse her as an extrovert.
her representative animal is a raccoon ( 🦝 ) and her color is khaki green.
she was scouted in 2020 when her dance practice video blew up and a manager noticed her — her rhythm and style was like none other and a few meetings later, she was on a plane to korea for training.
내 티, five bucks, 바지는 만원
before debuting, ryō had been dancing for years — mostly hip-hop and freestyle — and she used to style her friends’ crews for performances. she grew up surrounded by creativity: her dad’s old-school playlists, her mom’s eye for design. it all shaped the way she moves, thinks, and expresses herself.
in the group, ryō’s everyone’s go-to person — for advice, outfits, or just a good laugh. grounded but never boring, she’s got that mix of calm and cool that people naturally gravitate towards.
( and as for juhoon… let’s just say it’s not just friendship …. shh )

major ib to ninathefantastic, sorry for basically copying everything but she’s so aesthetic
Eden is the eighth member of the K-pop group named ‘Cortis’ in bighit entertainment and the third member of the girl unit ‘Aleys’ which means ‘Always love, embrace your soul’ (cr: gailu on pinterest).
Eden was the second member of ‘ALEYS’ to be revealed to the media after Iroha and before Yoonchae.
She is what the fans call the ‘member that was forced to be swaggered when she was born to be a pink diva’.
Along with Yoonchae, she auditioned to be in the dream academy but due to homesickness and the strong demands of Griffen, she left back into Hybe where she debut in Cortis and Aleys.
everyone knows this duo ! they met in 2021 after jourdain was given her first studio and martin wanted to visit it and before they knew it, they had been hanging out for almost the whole day.
they're known as prodz to fans as they have around 100 production credits combined, they're also known as tallz because of them being the two tallest in the group and towering over everyone they meet.
you won't find these two arguing almost ever..they eerily always have the same idea's for everything and basically agree on everything. in their old dorm they used to be roommates along with seonghyeon but having the three members who enjoy producing in a room together was bad news for the other three⎯ nights used to get way too loud in the old cortis dorm so for their new dorm assignments. seonghyeon got moved into juhoon and james' dorm and keonho got moved into martin and jourdain...nights can still get loud and unfocused, especially when packing.......but they know better for the most part
prodz have produced illit's magnetic after jourdain invited martin and james to help out on the track even while half finished, txt's deja vu and beautiful strangers, similar things happened for both of those songs and le sserafim's pierrot which she simply stacked her and martin's vocals after a night of what felt like throwing idea's at the wall and nothing would stick
they're truly a dynamic duo, they both look up to each other in different ways, understanding each other on higher levels having been trainee's for so long from such young ages, working so hard for so long. it would be crazy for them not to be friends anyways, plus, they both were given blonde hair for debut so you can tell how the other staff see the two also
The girls all sleep in one room with a bathroom for obvious reasons, with a bunk and a larger bed which was decided who slept where by a game of rock paper scissors.
The (og room is tripleS) room is usually where they play computer games or make music and often where Eden and Martin have ‘producer offs’ to see who makes better songs.
In terms of sleep, yoonchae sleeps first then iroha then eden who sleeps only with something playing on her phone. Also calling the others ‘grandmas’ for how early they fall asleep.
During these arena events Eden stuck mostly by the girls due to their own photos and content (just during the beginning). But after she honored the event as someone close in her family played soccer and prided in it.
Most of her fans trended her for flinching at the bird that was there and given to Sean (Seonghyeon) and kicking the ball during her turn in such a fast curved way that landed a perfect shot.
All in all, fans pointed out how the group matched in chemistry and growing camaraderie.
