YES I wanna know this too. But judging from the plot it feels like Ritsuka may have not been apart of the original band? I don’t think it’s physically impossible for someone to be a support for 10 whole years while juggling another band :,( kinda bummed out actually. Especially when Hiragi had balls of steel to take Ritsuka away ?? Got me kinda annoyed and now we see this. So in a realistic standpoint, i don’t think Ritsuka would have been apart of them sadly. Tho Haruki and Mafuyu are still sorta connected because there was some sort of “afterparty”?
They are all still together in a band.. you guys can read here.. https://www.mangago.zone/read-manga/given_the_10th_mix/
I don't follow the story quite often but what is our band's position in this timeskip? Why is Ritsu still a support guitarist after 10 years. I wanna see my boys attain success too in the music industry tgt
