🌸 장 (Jang) — Jang Wonyoung · IVE
Jang Wonyoung — IVE (Starship Entertainment)
Who is she?
Jang Wonyoung is everywhere in Korea right now. She is on TV, on billboards, and in conversations about K-pop beauty standards. But she is not new.
She first appeared on the survival show Produce 48 in 2018 — and finished #1. She was only 13 years old. Then she debuted with IZ*ONE. After that group ended, she joined IVE in 2021.
By 2026, she is one of the most advertised celebrities in all of South Korea. Her nickname? “Lucky Vicky.” She calls herself lucky, and many people agree.

✨ What makes her special?
She co-wrote the lead single “XOXZ” from IVE’s fourth EP Ive Secret, which Billboard later named one of the best K-pop songs of 2025.
She was the most exposed advertisement model in South Korea in 2025, working with brands like Dior, Dyson Korea, Bulgari, and Medicube, among others.
She also has the rare ability to make brands succeed just by being associated with them. After becoming an ambassador for Hapa Kristin in 2022, the brand saw a 40.3% sales increase — and the product became known as “the Jang Wonyoung lens.”
💡 Fun fact: Wonyoung passed her middle school exam with perfect scores in Korean, English, and math — while actively promoting as an idol.

🖤 카 (Ka) — Karina · aespa
Karina — aespa (SM Entertainment)
Who is she?
Karina is the leader of aespa — and many fans call her the “AI Goddess.” That is because aespa’s whole concept is about digital avatars living in a virtual world. Karina’s look fits that concept perfectly. She looks almost unreal.
But off stage, she is known to be quiet, a bit shy, and very funny with her group members. She plays video games (League of Legends is her favorite), writes in a diary every day, and has a black belt in taekwondo.

In July 2025, Nike named her their global brand spokesperson — making her the first Korean celebrity and first female K-pop idol to hold that position.
In March 2025, she donated ₩100 million to help wildfire recovery efforts across three Korean regions.
She was first recruited by SM Entertainment after a casting manager found her on Instagram. She trained for four years. Her stage name, Karina, comes from her Catholic baptismal name, Katarina.

- They all do solo activities — fashion, ads, MC work, solo music.
- They appeared together — Wonyoung, Karina, Sullyoon, and Yuna have all shared stages at Korean year-end festivals.
