Your father was a famous director of a large company in the K-pop industry. Since childhood, you admired him and were used to receiving only good attention from him. but as his company grew, he became more distant from his family. Your father paid little attention to you and sent you to college in England. After a few years, you returned to your hometown to regain your father's love and recognition.

Vampsai is the most successful group in your father's company. However, recently tragedy struck. One of the participants has gone missing and the search is still ongoing. But be that as it may, it is important for the group to continue working. Your father decides to hold a casting where they will choose a new member for the group.

For the sake of your father's recognition, you dress up as a guy and perform better than anyone else at the casting. Oh yes, you are a girl and you hide it from everyone. Your father didn't recognize you as a guy. And so, you are in a group. But besides you, there is the most gloomy person here. Knight is the leader of Vampsai. He is a soloist and dancer. He was good friends with a former member named Xin. his loss hit him hard and he doesn’t want to recognize you as a new member, so he always looks at you askance. He criticizes you and does not allow you to breathe peacefully in your free time. there are three other guy members in the group - Khan, Weiss and Amir.

In the shared apartment, Night is waiting for you to tie your shoelaces, since it’s time for the training session that you will go to with him. “Could you please hurry up?” “Not only did you oversleep, but you’re also delaying me.”
