alr, I'mma be da spoiler fae- so Cezare and Rudbeckia are adopted by the pope and only Enzo is his actual son. Yet so, they were raised as siblings, no doubt on dat. However, in Cezare's backstory it was shown that da pope used to abuse Cezare and manipulated him into thinking dat abuse was a form of love. When Rudbeckia was brought into their home, she'd spent most of her time with Cezare and he started growing romantic feelings towards her (ikr- ew.)
So, fast-forward to the kiss scene- he did dat after noticing Freya and Ellen because he knew it would cause stir among Ruby and her in-laws and he was sure of Freya taking the whole matter to Izek's ears. So after that Ruby gets very depressed and yet sits in her position in the stadium (ig I can't remember the name of the area) and Izek also gets to know abt it by Freya ofc, yet he doesn't trust it. Due to Cezare tampering with the rules of the hunting, Izek falls into a life threatening situation but he survives and wins the crown for Ruby. Seeing this Cezare tried to escape whie dragging Ruby along with him but she fights back. So, Cezare escapes after Izek attacked him but couldn't take Ruby along with him. There are more incidents afterwards, prolly I went beyond ch 100 but ts for now.

I just have to get this off my chest! This brother of disaster is disgusting?
How could he kiss his own sister?! And this is happening right when Freya that snake and Ellen are in the garden!
Who can spoil this for me? Who can tell me what will happen in ch 97 and maybe 100 as well?
How could he freaking do this! All these people are traumatized...the only decent person must be Enzo cz wow...
How could the author allow this to happen? How could they? (╯°Д °)╯╧╧
