I think there are plenty outstanding reviews of this drama & I agree with all the flaws. However there are few great minor characters that I thought were the only positives of this hard to watch drama.

1. ML's Manager. He's an outstanding character. I loved all his scenes.
2. Female producer who just blurb out brutal honest comments for the comedy relief.
3. Female makeup artists for the show. Few funny moments but highlight of the drama.
4. Male ex co worker -- "Dimples" Seriously he doesn't need to say anything, those dimples are just worth seeing
5. ML's CEO - few humorous lines.
6. FL's Dad - Hilarious!

In the end you can't really out act a terrible script. I pretty much skipped all 2nd couple's toxic scenes and somehow manage to finish.
