His Carnival (Yandere Taehyung ff)

Kim Taehyung was born with a rare and strange feature, red eyes. As a result, his own mother, out of fear and disgust, sold him to a traveling circus where he would be starred as a freak. He lived his life in ridicule and abuse, until one day he meets a girl who pitied him and showed him kindness. He becomes instantly enamored with her and from that day on he is determined to make her his, no matter what it takes.
