This drama was a rollercoaster of emotions and yet it was still hilarious throughout because of the leads and their bickering.

PERFECT CAST with AMAZING CHEMISTRY between all the characters, especially the leads. I need Ztao and Zu Er to be the leads on another drama together. Their characters had a wonderful love/hate relationship for each other. Qian Wei genuinely disliked Lu Xun (reasonably so) but Lu Xun had been in love with her for 11 years.
The BEST thing about their relationship is the fact that despite the fact that he was always in love with her, he didn't treat her like a 'lover' like in one scene in episode 1 where she was about to fall into a pond (of sorts) with her bag that carried evidence, instead of helping her, he snatched the bag and watched her fall into the water. That scene is exactly how their relationship is throughout the drama. It's no wonder she never figured out that he liked her.

It had the BEST and consistent WRITING. It started uphill and stayed uphill throughout and it revealed every single detail of the plot, so there were NO potholes or open/unsatifying endings to any of the storylines.
The relationship between the leads never changes, they bickered all the time whether they were a couple, rivals at university or boss/employee. I loved their boss/employee relationship because it never seemed like he was her boss with the way she treats him but the way she talks about him makes it sound like he was a terrible boss to her, which we never actually see because as the audience we know that he is in love with her and is trying to help her by making her read so many cases and do so much work.

I LOVE that we got to see Qian Wei's dream of re-living the past (seeing things in a new light and discovering Lu Xun's crush on her in real life) and falling in love with the young Lu Xun.
We also got to see quite a lot of Qian Wei and Lu Xun's actual past together and why their relationship is the way it is in the present.
Unlike every other time travel/ alternate dimension/ dream world dramas Iv'e seen or heard of (I've seen a LOT), this is the ONLY drama I've seen where the plot focuses on both the dream work and real world. The drama doesn't end after the dream ends, we got at least 10 episodes set in the real work and we got to see the leads fall in love in the dream world and in real life

Lu Xun is like the typical second lead, which he actually was in Qian Wei's actual past whilst Chong Wen the actual second lead, lived the life of a main lead in Qian Wei's actual past and for the 11 years leading to the present. this drama really showed Lu Xun's turn around from second lead to main lead (in a drama world). I tend to get second lead syndrome a lot in dramas, especially because a lot of the time the second lead is better than the main lead in every way and this drama showed the perfect ending of the second lead becoming the main lead.

The meaning behind this drama is that you can't change the past. Qian Wei spends a lot of this drama trying to change her past thinking her dream is real and even then, she couldn't change her fathers death but she was able to accept it and sort of be at peace with it (because his death gave her so much trauma at first that she couldn't be a lawyer by passing the exam). Despite the dream not being real, she was able to turn her life around for the better after waking up. Her dream helped her get over the past and straighten out her reality in the present.

I LOVE Ztao's OST for this drama. I can't stop listening to it. I also recommend looking up the English lyrics to the song because it fits PERFECTLY to the plot of the drama, here is some of it (the only one I could find that made sense):
"You are the rest of my life
My love for you is more than a billion stars
Even if we live in other world
I'm still all about you

I got a crush on you bae
I can't hide all my feeling
Do I still need to prove it?
You Know how much I love you
All the rest of my life is about you"

Seriously, Lu Xun waited 11 years to be with Qian Wei, he had a crush on her for YEARS. Though I didn't feel bad about his wait as much as I thought I would because he was terrible at showing her he liked her. He was "mean" to her face and did so much for her behind her back and never wanted her to know about what he did. He dragged his confession for 11 years and was unwilling to confess to her altogether, it was his fault for not telling her he liked her from the start, a typical second lead (though he is the main lead).
