Usually, I try, really, really hard to figure out what the writer/director/actors are thinking and find something clever, or something to redeem it.

In this case for a scant 4 episode Ren Jialun and the brother character are the only things to hold onto, until the director mind numbingly reins it in by episode 6 and I don't know why he did that because that's the only reason I was watching this drama.

For a story to work, you need one of the following things pretty much internationally to hold it together:
1. Characters want something they usually can't have or currently attain.
2. Characters NEED something they aren't aware of, but are promised to attain.
3. There is an established tone that the story promises to work on later to develop (admittedly, more of a Japanese thing).
4. There is a theme the drama promises to develop and tease out, then maybe twist later.
5. If you have none of those, and just characters running around, then the characters should at least be interesting until you can find the central event chain.

Guess what? The director/writer (same person) manages to cut this off by Episode 6. And struggles so hard that he has to include an unnatural event chain by episode 7-8. (i.e. it drops in rather that it blooming naturally out of the characters interacting with the events/tone/theme and then they create new events which then shape the character, etc.)

And then, OK, maybe you don't care about the previous, no plot, no interesting characters, but you want some knowledge base about *something*. Slow clap to the director/writer. You're denied. Because he constantly copy-pastes the top results from the search engine to make the psychologist character work. He doesn't understand anything about how it works. In Mr. Bad, which had less episodes, and a writer who has had, count 'em 2 scripts, they managed to include more psychology in the span of 2 episodes than this drama has in 8 and validly so. The script writer for Mr. Bad applied the basic principles of research, understand, and then integrate. Here, there is none of it. Meaning that a cotton candy Romance drama with half the episode count (about) managed to do more in research than this one did.

I've watched utter trash, but this is the first time I've witnessed a drama have no genre for over 6 episodes and still feel directionless for 8 episodes. And to be clear, I'm familiar with early Chinese dramas too, where it took a long time for the pitch, but in the long time setting up the characters, the drama promised a direction, kept good camera language, such as keeping the camera on the female lead for more than three seconds, and might even set up a theme, even if the events didn't really move. Using clever camera tricks for the sake of it is sooo rookie. In romance holding the shot and letting the actors emote is much better.

This drama has an utter gift to manage to not do that. And it's not that I don't understand "high art" or lack patience. I've watched Being John Malcovich, and really artsy pieces. I've also watched utter trash, and this drama manages to mindnumbingly surpass the fail for "Watch this for B-move entertainment", watch for an actor because they are trying something new and also feel so in love with itself while failing, that I want to cry.

The music is rated lower because he uses classical pieces so he didn't have to pay for a music director, and so he could get lots of unnecessary special effects like cars flipping over.

This would be my recommendations to the director/writer:

How you go 20 years in the business and manage this hard to fail is beyond me. I'm open to artists improving and changing, but stop copy-pasting from the internet and try to grasp what the articles that contain the definitions are saying about the item. Go and experience it, or ask experts. Make the characters WANT or NEED something, and if you're advancing in the ranks, you'll choose a theme and tone. And if you're trying for romance, the meetcute should be in episode 1, not 2, or a really good promise made in episode 1 on how they will meet and how epic it will be when they do (Outlander does this, US drama). If you're trying a new genre, get a supporting writer to help you out, OR do the thing that the Hong Sisters do, which is find a work to adapt so you get what the genre expectations are. Also, it's better to not self-glorify. And stop reining in actor's improvisation. Ren Jialun acting a bit overboard was the best. Him having multiple takes included, and acting overthe top was soo good--play on that, alter the script on that, let it be the plot. Pick a direction ahead of time, and integrate it throughout, and you might find your episode count is only 24 episodes. Hiring good actors to do scripts as poor as this is a crime. I hope the actors were paid well at least...
