With Dasom's evaluation by Woojin, and what she actually want to do, i just thought of a plot twist.
-time skip until dasom is in HS at least. Woojin is satisfied with his life and he take a backseat. working only as a producer. Hence his fame starts to die down.
-Woojin dies somehow
-the system is inherited by Dasom, and Dasom start to unleash her full potential.
-that way Dasom will become the MC, and the title will make sense.
