I watched izna - RESCENE episode, and I can only see Sarang

They say she was born in '07. She gives off a bit of a young Irene vibe.
Her visuals are exactly the SM style, but she debuted through the YG side (Teddy).
Anyway, while watching the video, I couldn't see anyone but Sarang lol
Ps. What are some famous songs by izna?
