2017

in 2016, eurydice was taken under the wing of blockberry creatives music producer and creative director, jaden jeong. her first project was for loona’s subunit, odd eye circle’s first mini album, mix and match. listeners can easily identify early traces of eurydice’s style through the heavy use of synths, creating an other-worldly listening experience. after the success of mix& match and max& match, eurydice continued her mentorship under jaden jeong to compose and write songs for the subsequent loona members,

[C] loona/odd eye circle: mix and match : ODD

[C] loona/odd eye circle: mix and match : Girl Front

[C] loona/odd eye circle: mix and match : LOONATIC (english version)

[CW] loona/odd eye circle: mix and match : LOONATIC (english version)

[C] loona/odd eye circle: mix and match : ODD front

[CW] loona/Yves : New

[CW] loona/Yves : D-1

[W] loona/Chuu : Girl’s Talk

2018

at the end of 2017, eurydice was scouted by lee soo man and became a trainee under sm entertainment under the condition that she would still be able to compose songs for blockberry creative. unbeknownst to her, sm entertainment would send her to a survival show a few months after she entered the company, halting all her activities. thus, eurydice was only able to contribute in 2 songs for loona’s first ep [++]

[CW] loona/Olivia Hye : Egoist

[CW] loona: [++] : Heat

[CW] loona: [++] : Stylish

2019

fresh out of the survival show in 2018, eurydice composed 3 tracks for loona’s first album [XX] before blockberry creative forcefully cut all ties with her, deleting her joint-project with jaden jeong ‘La Maison’ and all her other demo’s on her work laptop. thus, eurydice was unable to complete ‘hyper ballad’, and only the demo version was included in the [XX] track list. this would be the last time eurydice is seen credited as a composer for loona.

[C] loona: [XX] : XX

[C] loona: [XX] : Butterfly

[C] loona: [XX] : Where you at

[C] loona: [XX] : HYPER BALLAD (leaked)

2020

preparing for her debut in aespa, eurydice had little time to compose songs. additionally, as they were a rookie group with new strict rules placed onto them, eurydice found it hard to send her song demo’s to other artists outside sm entertainment. however, her 2018 untitled song demo, which was heavily inspired by hotel lobby music, found its way into dreamcatchers new album, crediting eurydice as one of the composers for the song. eurydice was shocked when blockberry creative used one of her completed demo’s in loona’s latest album without crediting her, but fans figured out through her distinct sound that eurydice had composed the song.

[C] Dreamcatcher: [Dystopia: The Tree of Language] : Jazz Bar

[C] loona: [#] : #

2021

after settling down in aespa and getting used to the hectic schedules, eurydice found time to write and compose more songs. eurydice initially wanted the songs to be for aespa, however sm entertainment denied all her songs for use. fed up that she was not given any creative control over her group, eurydice gave away her songs to chungha and belift lab. (at that point eurydice did not know belift lab was under hybe) ‘drunk-dazed’ and ‘fever’ were instant hits, topping the charts on melon and when sm entertainment found out that it was eurydice who had composed and written the song, eurydice was punished by confiscating her song writing journal and mobile phone, cutting off her connection with the outside world for months and preventing her from making new songs.

[CW] Chung Ha: Querencia : X

[CW] Enhyphen: CARNIVAL : Drunk-Dazed

[CW] Enhyphen: CARNIVAL : FEVER

2022

eurydice was really bored without her phone. by cutting off her access to music, eurydice was left humming melodies to herself, which was how she created the main melody of tripleS’s songs, with different interpretations of ‘la la la la’ that she sang to herself when bored. once her mobile phone was given back to her, eurydice immediately sent the demo’s of her new songs to jaden jeong for his new girl group tripleS, as a thanks for mentoring her years ago. leading to the release of the 3 tripleS songs in 2022, co-composed and co-written by eurydice.

eurydice also sent the lyrics of her song ‘pretty boys’ to yena, her close friend from produce 48, who was gearing up for her debut.

at the start of 2022, eurydice was contacted by 131 label as a feature in B.I’s single BTBT. although sm entertainment denied the opportunity for collaboration, eurydice kept on pushing for it as she had a feeling that the song was going to be a major hit, which could help boost her popularity and aespa’s. even though she was only supposed to be a feature for the song, eurydice had strong opinions on how to better the song, making it more appealing to audiences. this lead to eurydice gaining credits in production and lyrics of the song.

[W] Yena: SMiLEY: PRETTY BOYS

[CW] tripleS: Acid Angel from Asia <ACCESS> : Generation

[CW] tripleS: ASSEMBLE : Rising

[CW] tripleS: LOVElution : Girl’s Capitalism

[CW] B.I : BTBT ft. aepsa’s rein

2023

another one of eurydice’s old hotel lobby music demo’s was discovered and used in yena’s song love war. with the loona members joining new companies, eurydice was kicked back into full gear, composing songs for her loona-girlies in support of their debuts. eurydice also got the opportunity to collaborate with other producers to create ateez’s song, bouncy, which was an extremely upbeat song reminiscent of drunk-dazed’s ending.

[C] Yena : Love War

[C] artms/odd eye circle: <Version up> : Je Ne Sais Quoi

[CW] Heejin: <K> : Video Game

[C] Loossemble: Loossemble : Colouring

[CW] Loossemble: Loossemble : Strawberry Soda

[CW] Ateez: THE WORLD EP2 OUTLAW : BOUNCY (K-HOT CHILLI PEPPERS)

2024

back at it again with jaden jeong, eurydice helped compose the key melody of tripleS’s highly anticipated ‘Girls Never Die’, and ARTMS first group song, Birth, a in their first album, <DALL>. additionally, eurydice also helped compose and write ‘The Hitchhiker’s Guide to the Galaxy’, reminiscent of the unique loona XX sound that eurydice brings to the table.

[CW] tripleS: <ASSEMBLE24> : Girls Never Die

[C] ARTMS: <DALL> : Birth

[CW] ARTMS: <DALL> : The Hitchhiker’s Guide to the Galaxy

‘aespa’s black cat’

known as the 4th generations ice princess, haerein’s natural stoic face competes with the likes of jessica jung and krystal jung, making netizens often joke that she is their estranged sister.

as aespa’s leader, haerein often finds herself in situations that puts her way out of little introverted bubble such as giving acceptance speeches for awards or introducing her group to her senior idols. but work is work, and haerein performs her leader duties with due diligence, never failing to speak up for her members and give her feedback and inputs on the situation at hand.

off-leader mode haerein is shy and introverted. when conversing with a group of strangers, haerein goes mute and prefers to listen to their conversation as if it were a podcast. haerein is known to be quiet and observant amongst her colleagues.

with her close friends, the ball of energy within haerein is released. loud, energetic, affectionate, haerein’s personality takes a complete 180. clinging onto her close friends like a koala as she yaps about everything and anything, the chatterbox is known to set the mood of conversations

although her mbti is a T and not an F, haerein is big on empathy and is always in the background making sure her members feel comfortable and well-rested.
