A story that shows the reality of kpop idols and trainees

I've seen many idol romance drama but this one is different. It actually feels very real. Idols' and trainees' struggle, their hard work and passion all are covered in this drama.
It shows what struggles the people of the industry have to face to achieve their dream. And how they fight together to fulfill their dreams. Though only 0.1% of the trainees can debut , they fight until the end.
It also shows that how the decisions or choices we make impacts our lives.
Really a heart warming feeling. Loved it.
