So, I recommend you

Ai Endo (Yuki Sakurai) ) is a typical contemporary urban empty office worker. She cares very much about what others think of her. She can be said to be a woman who lives in the evaluation of others. At nearly 30 years old, her love life is blank, and she is engaged in the boring life of an office clerk. Day after day, year after year, Endo Ai gradually feels tired and suffocated. By chance, Endo Ai broke into the performance of underground idol Kurimoto Hana (played by Shiraishi Sei). Seeing Kurimoto Hana on the stage, Endo Ai seemed to see herself. Ai Endo immediately became a fan of Kurimotoka and supported her at all costs. In the process of chasing stars, Ai Endo gradually discovered the true side of herself that had been suppressed for a long time.
