I will say the adaptation is the best, they remove some scene and make link to every story arc so is fit 38 episode.

Jiang Xue Ning, she is someone who has regret and willing to fix it. She try to help people around her and changing their fate for something better, she's not perfect but she'll try.
Xie Wei, he complicated person. He use to have everything then lose all of it in a day. He had traumatic past, he know that people is cruel. Like he said he is not a saint. He schemes everything not care about the world.

Their relationship grow a long time, JXN use to afraid XW but then she became to trust him.

For novel reader the ending little bid difference, they tone down some character. They connect story so is more fit and not feeling rush. And of course is HAPPY ENDING.

For me is pity they don't make longer episode, they are a few scene from novel I think gonna make this drama more greater that ever.

BEST
