After the protagonist Eun-hee was reincarnated and joined the popular Asian idol group EXO as the thirteenth member, she got to know, get to know, accompany, and stay with the other 12 animals. They laughed together, ups and downs together, were strong together, and harvested the touch of life together. In this mixed entertainment industry, 13 teenagers went from ignorance and ignorance to maturity and stability. Everything has changed, but nothing has changed. There is nothing about love here, some are just the intersection of friendship and family; some are just the battle between people's hearts, good and evil, beauty and ugliness; some are just growing up together and helping each other. (It will involve people and things in real life. This is actually mainly based on reality and imagination, please don't mind)
