Is Uncle "Kiyomi" Ade a good guy or a bad guy?

Uncle De in Kiyomi is a master in the field of antiques, and he is best at restoring antique calligraphy and painting. Zhuang Rui is his student, and Zhuang Rui has always benefited from the care of Uncle Fred. However, the audience couldn't figure out Uncle De's personnel.

Zhuang Rui went to work as a pawn shop, which was introduced by Uncle De. If there is anything in Zhuang Rui, the first person he is looking for is Uncle De, and Uncle De is also very keen on Zhuang Rui. For Zhuang Rui, Uncle De is his teacher and his relatives.

However, Uncle De is actually a super villain. Maybe he was simple about Zhuang Rui at first, but since he learned that Zhuang Rui had Kiyomi, De Shu is no longer the original De Shu. Now that I think about it, some of Uncle De's behaviors are suspicious. Maybe he knows that Zhuang Rui has a golden student.

Uncle De's reputation is ruined:

Uncle Fred helped Zhuang Rui so much, but he knew his value and wanted to use him. Finally, Uncle De was naturally discovered by Zhuang Rui, and their relationship broke down. At the end of the ending, Uncle De was also ruined.
