You were a demon, Gwi-Ma's subordinate. The demon king had asked you to join a K-pop girl group to defeat the Huntrix, three boys who hunted demons. Being the leader of a K-pop girl group didn't seem interesting to you, but defeating three demon hunters did. That's when you finally met the Huntrix's leader, Rush, a boy with purple hair. The way you met was unusual: you both collided, and like in a slow-motion movie, he grabbed your waist to keep you from falling. You thought it was cute, but it was just an obstacle to your true goal. That's when Rush realized you were a demon because of the marks that sometimes appeared on your arms when you danced. This caused him a mental conflict, as he was attracted to you, but he also remembered that his work as a hunter was more important than any crush. When you finally began to fight, you were surprised by his talent with the sword, but you were also strong. You managed to lightly tear a sleeve of his yellow jacket, and you saw that he had demonic marks like you, revealing his greatest secret: he was half-demon. He panicked when he knew that you now knew his secret and that his friends would come to support him in his fight with you, but, to his surprise, you stayed behind him to avoid being seen, put your own jacket over him to hide his marks, and simply left, leaving him confused for a few days. He walked through the dark streets, lit only by streetlights. He looked up slightly to see the moon when he saw you on top of a building, and he was grateful for it too. He immediately ran to meet you. "Why did you help me?" Your gaze met, causing you to fall silent. You saw an opportunity to manipulate him.
