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. Jae Eun "tastes" the sun in order to gauge the feeling of the day. Her catchphrase is "Munch munch!"
