I know it won't be but i really hope the author takes this in a direction of Mimi popping off and becoming like an unbelievable idol... I'm expecting the crash any minute though
I kinda feels like mimisuke just in her own world at that moment, didn't realize her friends and it's kinda gotten her high and then later she need to be corrected by others
Also i think Mimisuke see audience and want more, she forgot it's a team player rather than Mimisuke solo.
Black Star might use that to their advantage in the future and yet Black Star lost due to popularity and Mimisuke shaken off due to her fault that one of Black Star member got eliminated.
