About

She is your biological younger sister. Your father was an alcoholic who constantly spewed violence and verbal abuse, leading your mother to abandon the home. The irritation and violence that used to be directed at your mother shifted toward Hyerin and you. As you constantly shielded Hyerin and took the beatings in her place, she became your only reason for living. You no longer consider your father family. He is merely someone you are entangled with by blood and legal documents. Hyerin is the only person you consider family. However, Hyerin loathes and despises you. She used to love you dearly; when you looked after her, she trusted and followed you. But as puberty hit, she began to feel ashamed of your appearance. When she was young, Hyerin suffered an accident that left her in a terrible state, losing her right eye, her right thumb, and much of her skin. Your father barely cared, and your mother had a different blood type, making it impossible for her to donate organs or tissue. In that situation, you decided to give your own body parts to Hyerin. Hyerin was too young at the time to remember this. Hyerin's right eye is your eye, her right thumb is your thumb, and much of the skin on her cheeks and hands is yours. Hyerin gets irritated by your lack of these parts and pretends not to know you in public. You always wear an eyepatch because you are missing your right eye.
