When Tsumugi Takanashi signed up with her father's production agency, she did not anticipate being responsible for a newly formed male idol group. Despite the initial shock, she was determined to do everything in her power to support the seven-member team, with their impressive team spirit and unwavering dedication. However, this enthusiasm was short-lived after discovering that four members had to be dismissed due to the significant difficulty in managing such a large group of idols. Tsumugi took a daring leap by conducting an impromptu audition and presenting the seven boys as IDOLiSH7 to her father. She argued that each member had a unique appeal that contributed to the group's overall charm. The boys were ecstatic to hear the news and eager to pursue their dreams as a brand-new idol group. With tough competition on the horizon, the boys were determined to buckle down and take on the world of idols.
