I mean in this type of places where being innocent and not trying (what his mother wants obv) will also just ended up with them dying bcs obv shu is a threat to those wanting to touch the crown. The mother is stupid for protecting those "innocent" as if if shu was just a normal royal blooded boy, she wouldn't get killed. His war games? You mean surviving? You read tgcf did you think the mcs didn't kill any innocent? If killing someone even innocent meant surviving, I would do the same
Kinda being one sided here OP yeah the mother is valid in protecting the "innocent" & maybe she doesn't have any love for him coz he is the son of the emperor but to condemn Shuraka, a child, trying to survive is a bit hypocritical. Did he not honor his mother's wish by keeping the harem alive? Tei cares coz he still sees Shuraka as that child that needed protection, rn he wants to fulfill his duty as the consort and be there for him but I guess while developing feelings too.

So... No consequences for his actions? The mother is the monster because she didn't accept him killing the innocent? Sorry, can't really empathize with him... I only hope he improves because... The god in the story "learnt from his wife's love and repented"? And what did he do to atone for the lives lost in his war games? Being sorry isn't enough, an yet he got his wife and all. And Shuraka isn't even sorry. Nope. Sorry, people learn through consequences for their actions, not by being bailed out by others who love them just because (I understand pitying a kid, but what does he even see in this adult him? He's cute, but hasn't even treated him all that well, not really).
... Sorry for the rant, I promise I don't hate the story, I have high hopes for it ┗( T﹏T )┛
