In "Happily Unmarried Girls" (비행소녀), actress Lee Chae Young (이채영) describes herself as a travel addict, full of wanderlust with an insatiable desire to travel. She has traveled extensively around the world and likes to keep mementos by stitching flags onto her travel backpack and creating a photo collage masterpiece of her travel experiences which is proudly on display in her bedroom wall. Aside from travelling, she likes to play video games, draw and paint, collect Ebichu plush toys and drink beer whilst absorbing the views from her stylish, modern high rise bachelorette pad.
