EDIT: I rethought and lowered my rating. But, I still stick to what I said.
Definitely, this drama doesn't deserve a 9.5 if you look at it from all aspects. But, I loved it so much to the point that I rewatched it.
So... is this really worth it?

THE CHARACTERS:
The usual: Yuan Qian, a freshman of the Sculpture Department has no time for games or relationships - she wanted to badly transfer her major to Oil Painting which she had unfortunately lost due to her low College Entrance scores.
Qin Shen: the hero whose heart is same as that of his sculptures. He doesn't pursue relationships either, rather he wishes to excel in his craft and talent.
They have their own paths. So, when they collide, thing go right and wrong.

SATISFACTION OR CAREER?
One thing that I absolutely loved is how they handled this subject. (And possibly explains my high rating.) Most of the plot revolves around the female lead attempting to change her major to the one she loves. Qin Shen, the male lead, is punished by his mother for choosing what he loves - sculptures. [ I didn't even know that such a major exists. ]
The school decides to stop taking in students due to its less popularity.
With only 11 students and not to mention that most of them were reassigned from other majors and had to learn to love Sculpture. [Except maybe two or three including Qin Shen.]

Objectively, parents are right - sometimes choosing what we love would end up with us being jobless. I still don't know what to think of this and it might never change.

THE ROMANCE:
Coming from a Professional Single myself, I would not ask you to trust my rating.
The leads are forced together on several occasions, which I think is the reason they fell for each other. There are time skips right from EP 3, so we do not see the complete growth of their relationship, rather only the tough parts.
I liked how Qin Shen and Yuan Qian were skirting around each other without ever telling what the other was feeling. This leads to some misunderstandings. (They don't get together until EP 16.)
Heck, Qin Shen himself is one jealous person. But, I wished Yuan Qian had tested his limits cause most of the time, it seemed like she didn't. She was afraid of losing him once she got him.
And I've seen comments about how Qin Shen's actions creeped out many. I suck at anything romantic, so I'd suggest you to watch the drama to find out. I didn't care much about the last few episodes, even though I loved the drama.
And this comment sums up what I thought:

[Same thing with LoveO2O - Wei Wei's computer was hacked by the main guy, not to mention that he almost stalked her albeit his intentions... if it was real life, he'd be in jail.]


THE FRIENDSHIPS:
They were one of the reasons that kept me watching the show. All of them were unique and relatable and reminded me of my real life friends. Particularly Chen Qinan and Yi Ming.
I had many crack up moments due to their antics.
For once, there was no "you are better than me" "she is more good looking" talk among them, both girls and boys. They learn to appreciate each other for who they were.

THE ANTAGONISTS...
don't actually exist. The second lead, Song Siyi is never considered a romantic rival. He is good and cheerful to everyone, including the Yuan Qian. He might be even better than the male lead when it comes to possessiveness. But, its clear that what he feels is just his wishful thinking. He is one of my favourites for just being himself.

I didn't particularly hate Ling Wei either. She had a crafty mind, but she wasn't completely evil as some of the others I've come across.

OVERALL:
Its a good watch and throw drama among many of the millions released every year, if we ignore the problematic parts. But, I'm glad that I stumbled across it.
