Before ifeye
Kasia entered the public lineup first, revealed in October 2024 after training under the temporary label Trainee S# U. Her audition history stretched beyond Hi-Hat, and she performed CHUNG HA’s “Snapping” choreography for the audition that mattered.
What Kasia Brings to ifeye
She is the line between cute and sharp. When “r u ok?” needs the mood to stop being polite, Kasia is usually standing near the switch.
Career with ifeye
Kasia debuted with ifeye on April 8, 2025 through ERLU BLUE. The July comeback sweet tang and “r u ok?” gave the members more room to show individual rhythm, vocal color, and camera personality.
Reveal and debut timeline
Hi-Hat Entertainment revealed Lee Ga-yeon in October 2024 during the company’s pre-debut trainee rollout. When ifeye’s final identity was announced, she adopted the stage name Kasia and entered the six-member lineup with Won Hwayeon, Taerin, Rahee, Meu, and Sasha. Her personal group timeline begins with ifeye’s official debut on April 8, 2025.
The group debuted with the digital EP ERLU BLUE and “Nerdy.” That title is the correct starting point for Kasia’s official recording and music-video history. Pre-debut dance or trainee content documents preparation, but it should not be counted as a released ifeye song or an independent solo career.
Leader and main-rapper role
Kasia has introduced herself as ifeye’s leader and main rapper in official promotional interviews. Leadership in a young group is practical work: keeping communication moving, helping six members maintain a shared public tone, and carrying responsibility when schedules or interviews become unfamiliar. It should not be turned into a personality myth or used to assign her credit for decisions made by the company.
Musically, her lower and more rhythmic delivery gives contrast to ifeye’s brighter vocal palette. “Nerdy” establishes the group’s first version of that balance, while “r u ok?” from the July 2025 sweet tang comeback gives individual members more space to establish timing and camera identity. Official stages and dance practices are better evidence than short line-distribution edits.
Performance identity
Kasia’s performance strength is the shift between friendliness and sharper focus. She can stay inside the group’s youthful concept without smoothing every phrase into the same expression. Her rap tone adds weight when the production becomes especially light, and her dance timing helps those changes feel connected rather than inserted.
Because ifeye is still early in its career, permanent claims about range, songwriting, production, or a fixed hierarchy should be avoided unless official credits support them. Future releases will show whether her role expands. The page should grow with those records instead of filling uncertainty with recycled fan-profile claims.
Era guide
Begin with the official “Nerdy” music video and debut stages, then compare the sweet tang era and “r u ok?” performances. KCON LA 2025 material adds an international-stage reference point. Behind videos and interviews help document her leadership and communication, while dance practices reveal formation work that camera edits often hide.
YouTube tracking history
This profile tracks official ifeye music videos, dance practices, performance films, behind-the-scenes uploads, interviews, and broadcast stages featuring Kasia. The record begins with the 2025 “Nerdy” debut and continues through “r u ok?” and later official eras.
