What Works
What Does Not Work
Emotional relationship
What Works
The complicated bond between Pi O and Jeong Yo remains the drama’s biggest strength, with competition and resentment balanced by a strong emotional pull.
What Does Not Work
The story introduces kidnapping, apparent death, a lengthy time jump, and a revenge angle so quickly that some developments feel more dramatic than organically earned.
Time jump and pacing
What Works
The time jump effectively shows that Pi O’s professional success has not brought emotional fulfilment and allows Song Kang to portray his transformation.
What Does Not Work
The series sometimes adds another twist before earlier developments have fully settled, while the shift from music-school drama to disappearance mystery makes the plot considerably darker.
