The youngest girl in PURETTY, Jae-eun is one of the girls who came abroad from Korea to study the art of Prism Shows at the Pretty Top agency. She is a natural airhead, and is more than a bit clumsy. A sweet and honest girl. However, she is quite selfish, and a big crybaby. She falls in love quite easily. She "tastes" the sun in order to gauge the feeling of the day. Her catchphrase is "Munch munch!"
