Po begins a new job as a documentary director, telling the story of the final concert of the boyband Mars.  On his first day at the job, he immediately clashes with the band leader, Thame, who plans on leaving the band for a solo career in Korea. 

MARS and the company are shocked when Thame doesn't leave as planned for Korea.  As their work schedules align, an opportunity arises for Jun and Thame to make amends with Po's help.
