To be honest, I was expecting much more from this drama. The start was great, but the drama became boring very quickly, so I had to start skipping scenes. I really liked the past story mixed with the present. I wasn't keen on the idol part, as it was not very interesting and did not add much to the story. Also, I loved the brothers, but I was not a fan of the main female lead, as I did not like her portrayal of the character. I would prefer it if they concentrated more on the brothers' story. The drama has a great concept but failed to execute it well. Also, they could have done a better job of lip-singing, as every time the female lead sang, it felt strange.
For me, it was a waste a time.
