I’m lost but I don’t think Christoph is related to Ryan somehow;;I think he just reminds him alot like his sister that’s why he cares so much about him ??

I think the opposite. Ryan said the Christoph killed the culprit for poising him a long time ago. What if somehow Ryan's sister was the one who poisoned him and Christoph is her kid and she died giving birth to him? It would makes sense to say that Christoph "killed" the culprit. But I don know, I'm probably thinking too much since Christoph seems related to that man from the organization which took Kyon and Christoph on the past.

I think what happened was Intron/Edwin manipulated Christoph to get the servant to poison the Selvoir family. At the table drinking the wine was also Ryan, along with his sister and her husband (Lucaon's parents). Christoph was ordered to kill the servant who poisoned the family by Edwin, meaning Ryan could not have any damage done to his core reversed by the remedy of the culprit conveying remorse, seeing as he has long been dead, and it is now that Ryan is no longer able to fight his weakened core and he is dying. Ryan wants to wipe Christoph's memories of his time with him, in order to protect him from the reality that he played a part in harming his beloved Ryan.
Omfg... why’s he so angry at the last panel
Spoiler
I’m glad the raws are in Chinese and I could read them haha
The village is facing some danger and he was asking the uke to leave and go back to Japan in which of course the uke would not listen to him so he yelled at him to leave and the uke got shocked. And the bottom of the panel ends with something like “When their feelings are still in a state of confusion, there is more trouble to come?”
Omg thanks even though chinese is my mother tongue I can’t read it.. :”)
