The sound of a door creaking echoed throughout the near silent apartment. Clad in a pair of fitted black jeans and an black hoodie, a young woman walked in, carefully closing the door behind her. Her high top converse sneakers squeaked slightly as she took them off upon entering, letting her hood fall off the top of her head and releasing her long blonde hair from it's ponytail. She turned the lights on, looking around the small apartment. The time on her microwave read '03:22AM'. Sighing, she softly padded in her sock covered feet across to the room she shared with her sister, opening it slightly to see the brunette curled into a small ball on their shared bed on the floor. She closed the door and made her way over to their tiny excuse of a kitchen, taking out a sheet of fresh notepaper, she grabbed a pen resting on the counter and slowly started composing a note to her sister. 

"Hey Hayi..." 

Chaerin, a young woman in her early twenties is currently working 3 jobs supporting herself and younger sister Hayi. 

Hayi, a teenager, is a slightly awkward but very sweet young girl focused on studying so that she can do well and take care of her hardworking older sister. 

The sisters work on different schedueles and rarely see each other, so they leave each other notes as a way to keep each other updated on their lives.
