In Those Days(2021)

Having failed to get into graduate school, with no girlfriend, no money, and no prospects of success with his band, Tsurugi's life has reached rock bottom. One day, after watching the video of Aya Matsuura's song “Momoiro Kataomoi”, he becomes obsessed with the idol singers of “Hello! Project”, and plunges into the idol geek lifestyle. However, as time passes, he and his buddies all find other things just as important as the idols and begin to move on.
