Lost You Forever was my first time watching Deng Wei. Although he may not have the most experience in acting compared to many of his cast mates, he embodies the spirit of Ye Shiqi and Tushan Jing quite well.
The ending of S1 was hard to watch for me as it is arguably TSJ's lowest point. His full story and character arcs are not yet complete, and without knowing how things play out, to the audience, he may just seem like a kind-to-a-fault, weakling who can't even figure out what's going on around him.
But as this thread's title suggests, Jing's kindness is what the world needs. This may seem like a trite statement, but it's one of my favorite themes in the novel. In ch 34, after FFYY and TSH are caught in their schemes, FFYY says that she used to think Jing was weak and useless but realizes that to forgive requires true intelligence and strength of character. It's such an affirming moment - while it may have been more efficient to just kill Hou and FFYY, Jing would rather forgive and extend kindness - especially for the sake of his young nephew and break the seemingly endless cycle of revenge and violence.
Related to this is Jing's unwavering support for Cang Xuan. In such a dark, tumultuous world of Dahuang, Jing longs for a strong but compassionate ruler to ensure that all can enjoy a life of peace and prosperity. At the end of the novel, he states to CX that when he was learning to do business, he saw how many people were displaced by war and sought to support someone would would care for all the people (as CX does).
There's so much more to say, especially regarding the theme of healing, but maybe another post, another time.
