This Gong family tree sure did drive me nuts but I think I've figured it out (mostly)😅
So Gong family has four branches: Yu, Shang, Jue and Zhi
All 4 cousins are from one as is apparent from their names.
Gong Zi Shang
Gong Zi Yu
Gong Shang Jue
Gong Yuan Zhi
Now, I don't know for sure about Gong Huanyu's background but he is the bio brother of GZY as far as we can have been told. I have my doubts about this tho cuz was GHY a bastard then since during the Bride selection, GZY's mom was chosen and had him so who was GHY's mother??
Also, GSJ's mom and little brother(same age as GZY) were murdered at the same time it seems like from the trailer. I feel like maybe he protects GYZ so much because he is kinda taking him as a replacement for his biological little brother (kinda).
I am not anticipating a good ending for both GSJ and GYZ.
Also, can anyone tell me where you guys saw Prince Yue with Yun Que?? I've watched the scene where he was holding a bracelet when he was informed of Elder Yue's death but how did we figure it was Yun Que's bracelet?
