My first dream star

A 15-year-old girl who likes to dress up, Kim Ari! She goes to Jamsil and meets Yoon Seo-hyun, a girl of the same age who wants to be an idol.

Seo-hyun was a girl who practiced the knife group dance to find her mother, Lee Se-hee, who was a legendary star in the past. It just happened that there was a performance by A-teen, the group's most popular group, and the president of the group's management agency accidentally called the two to cast. Unlike Seohyun, who has honed her skills, Ari, who is not athletic, was embarrassed by the sudden audition. And another main character, 16-year-old girl, Lee Yoo-jin! Yujin has been a fashion model since she was young and her specialty is singing and dancing. With Yu-jin quitting her fashion model and jumping into the K-pop scene, the three-member idol unit, Sunny Girls, will make her debut. But soon before them, the newly debuted duo, 'Parana,' and the mysterious rising star Kang Ye-na will appear. Parana and Sunny girls grow up when they compete in good faith. Meanwhile, Yena, a 12-year-old genius prodigy, shows amazing ability to overpower the sunny girls and the parana...Who will be the best pop star?
