"I am your Karma. And I will not stand by in the presence of evil." Y/n is Yona's half-sister. King II had an affair two years before Yona was born. After y/n's mother died, King II took her in. Y/n envied Yona as she always received the love she never got. She also developed feelings for Hak but believed Yona would win in the end, so she gave up on love. Y/n knew what happened outside of the walls, from the starving citizens to the fire clans abuse of power. She leaves during Yona's 16th birthday on a mission. What happens when y/n and Yona's group crosses paths? Will y/n help Yona avenge their father or will she join Soo-won's side?
