Rosie is an art student though her parents would want her to be a lawyer like them and her sister, her parents knew it wasn't what their daughter wants so they let her chose her own path. 

When she was a kid—when her friends were playing at the park, she would just sit at the corner. She isn't really a social person. She enjoys her "me-time" so much so she pulled out her book and coloured pencils that she always had in her backpack and just freely draw things she saw; people, a tree, flowers. Her mom, of course, noticed it and after that, she bought her more coloured pencils and more books and Rosie's drawing just got better and better as she grew up—and she learned it all alone.

As she grew up as a woman, she took an interest in environmental drawing—as always but it's more often now. It somehow soothing her because she could feel the loneliness in her drawing, she could feel the urban feelings when she drew those—it really puts her in peace. This is why a park near her condo is her current favourite place for her to use her creativity. 

She drew a lot of things; a woman with her dog, a man jogging, a woman who feeds the swan near the lake—and of course, her favourite muse, a certain woman who always came at the park to jogs. This woman caught Rosie's attention so much that she didn't even realize she drew her every day.

She drew her when she's jogging, she drew her when she petted some dogs
