Lee Jieun is just like any teenage girl. She’s feminine, she can sew, she can cook… basically anything feminine. She is quite popular among the guys in her school, but isn’t called a queenka. Why? Because the queenkas in her school are mean, selfish, rude… let’s just say they’re es.

Just like anyone in the world, she has a secret. Her secret isn’t about a crush or something embarrassing. Her secret isn’t even close to those topics. Her secret is that her hearing is much more advanced than other people. Her hearing might be more powerful than a werewolf.

She inherited her ‘power’ from her mother. After her parents found out about her power, her mom gave her a ruby necklace. She was told to never take it off. Even when bathing. Her mother told her something, but she was too young to understand what it meant. So, she lived her life normally and peacefully.

Until she met Nam Woohyun.
