Cortis 6th member

Han Aerin never expected leaving Ireland to be the easy part.
Born between two cultures and raised thousands of kilometres away from Seoul, she arrives in South Korea carrying one suitcase, three languages, and a dream far bigger than she is.
Then she meets Martin, James, Juhoon, Seonghyeon and Keonho.
Somewhere between endless practices, late nights, inside jokes, cameras and the pressure of debut, five strangers become her members-and eventually, her family.
As CORTIS steps into the world, Aerin must learn how to grow up beneath the brightest lights without losing the girl she was before them.
The world knows CORTIS.
But this is the story of the sixth member who was there through it all.
