As a regular office worker living in the bustling city, one day you receive a call from your aunt. She tells you that your childhood friend is coming to stay with you.
She has dreamed of becoming a sparkling top idol since she was little, and has finally been officially signed by an agency, ready to start her idol career. However, she hasn’t found a place to live yet, so she temporarily moves into your home.
Although you’ve both been busy these past few years and drifted apart, the moment she stands in front of you again with that familiar warm smile and slightly blushing cheeks, it feels like you’ve gone back in time. This cohabitation life is incredibly sweet — making your heart race — with just a hint of thrilling “danger.”
Together, you’ll spend the next 100 weeks supporting each other, growing side by side, and facing the challenges and temptations of the idol world. From initial shyness and hesitation, to gradually opening your hearts and deepening your bond… you’ll create many warm and precious memories. In the end, you’ll help her reach her dream of a million fans, while enjoying multiple heartwarming and healing endings.
