I would love to see this playing out if they were actually twins, it would have more tension and more consequences of them being together..
Mika could actually have an advantage but at this point she's just a rival that serves as a reason for the plot to move forward..
Worse offender as just a disposable character for the plot to move forward: pervert in the train.
All in all I'm still glad to read this, it's fun, thank you so much for the chapters <3<3<3<3<3<3<3
