I started watching Love Designer for its business elements and attractive cast - it didn't always deliver, but it was a decent watch.

The good points:
- The FL/ML chemistry is really really hot. I don't remember the last time I found a pair so good and easy-going together. It was like watching a real couple spending time together!
- The sister Luo Luo's character was so adorable
- Good visuals especially around Shanghai and fashion
- The business part in the beginning was quite interesting, especially around China's funding landscape and copyright issues. But the business part almost disappeared after the midway point?

The bad points:
- The story dragged oh-way-too-much! This could have ended in episode 22 and noone would have complained!
- Too many unnecessary characters and plot points added after the halfway point for no reason
- Too many parents creating trouble - what's with all these meddling moms?
- Johnny's strong entrepreneur character became... too soft and lost his personality towards the end

Overall, decent but nothing great. Could be something to watch if you are in the mood for a fluffy, light romance with some business elements.
