I came into this show expecting nothing, but liking the clothing designer concept and the FL. I watched 10 episodes and even skipped to episode 14, but couldn't go further.

LIKES:
The FL's character and how the actress portrayed her.
The 2nd couple [FL's best friend and Glasses Boy (Allergic to cats guy)].
Cinematography was great and production was smooth.
OST was not over powering and I liked even the music used for the ring tones, but nothing stood out.
FX were minimal, but not overdone.

DISLIKES:
Male lead acted his part well, but I don't like how the writers made his character an over-the-top insufferable jerk. There was nothing charming about him. He deserves a woman like Luna to be his wife.
Also didn't like that they had the FL always walking in the middle of the road, like she's suicidal or just plain stupid.
Too many little side stories that weren't well written, which bogged down everything and no wonder it's 45 episodes long.
Too much product placement and some of it not even well done. (However a lot of dramas in China seem to have this issue too.)
The message of the show seemed to be more "don't try anything that you like, because you'll just fail."

OVERALL:
I don't know why everyone rated this so high, the ML's character has so many red flags! I wont watch this again and I don't recommend it at all. It was a waste of time. I kept hoping the ML's character would have some growth and not keep being such an @sshole, but he never changed.
