If the storyline is mainly focused on SOUL member's life,music,attitude,bromance,survival,fun,scandal,rivalary,etc, it will become better to watch instead of focusing love triangle between manger and idol members.

Thought I like the casts, story's background(entertainment industry), story is not realistic. Why male idols gp manager will be a female. There is no chemistry at all also.
If the character of female lead become idol or actress, it may be better.

There is no tempo also. Make me boring and angry when two main male lead become rival.

To conclude, ith Cha Eunwoo and Ahn Yoseop, the casts are worth to watch. Hope them to choose better script and director in the future.
