This drama was a masterpiece from start to finish, the main characters were incredible and super well developed. It's easy to understand Zhu Yun and agree with everything she does. As for Li Xun, whose behavior is unpleasant at first, we end up adoring him in the end, understanding all the suffering he has accumulated by being alone all these years.
As for the plot twist, I really wasn't expecting it, I didn't think Lao Gao was going to end up betraying them, I really liked this trio, I really appreciated that it had a happy ending despite everything that happened, I think Lao Gao had every right to get nasty with what was going on even if it doesn't excuse everything he did, but you could really see his suffering through the screen despite the horrible actions he did.
The romance between Li Xun and Zhu Yun was, in my opinion, perfect, the directors developed their relationship superbly and didn't rush it, and I also liked that they had a happy ending with everything they'd been through, they deserved it.

I also loved the secondary characters, especially those we see in the second half of the drama when Li Xun gets out of prison, the "My Heart Flying" team were really funny and united against any obstacle.

For me, this drama was a masterpiece and everyone should watch it at least once in their life.
